16" MBP GPU Panics

[cyprian.pl]

I picked up 2019 Macbook Pro 16" - manufactured early March 2020 and I have this issue.
I can reproduce it on a clean system - reformatted, nothing installed, single user created.
All I have to do is to play a youtube video and plug in my LG Ultrafine 5k screen.
I wanted to replace my 2016 MBP 15" but I'm sending the new one back.
Even if that's software issue this is clearly a no go. I got the top version.

After the issue occurs, the system won't even start up, it'll crash & reboot itself a couple of times (with 1 second fans blast).

I think I might headbutt a meathook.

Been having panics since yesterday on a brand new (2 weeks old) MBP 16. *kuch* Very much looking forward to finding a place where I can hand in my machine right now.
BTW: can confirm that 10.15.4 does not fix the panics.

*EDIT*: had 3 panics yesterday, > 5 today

panic(cpu 2 caller 0xffffff7f9221997b): GPU Panic: mux-regs 5 3 7f 1f 0 0 severity 3 WS-ready 0 switch-state 0 IG FBs 0 EG FBs 3:0 power-state 0 3D idle HDA idle system-state 2 power-level 5:0 power-retry 0:0 connect-change 0 : PowerPlay Failed Resume.

As you can see, my machine belongs to a January batch.

Its frustrating to see someone claiming its not hardware when APPLE ALREADY SAID IT WAS! If it GPU panics, its the hardware. If its slow, then it may be software. Apple's executive team told me directly that they are aware of a batch of MBPs that have a hardware flaw and they have rectified it. I can only comment on the panic.

Now that said, lets all maybe identify the CPU batches/MFR dates that have the panic issue using the Intel CPU. If you *panic* with a Powerplay Failed to Resume or Powerplay failed to initialize, please enter your serial number into this web site: http://www.chipmunk.nl/klantenservice/applemodel.html

It will tell you the manufacturer, year, month, and week.

Mine is manufactured by Quanta Computer, week 48, December, 2019.

One of my friends who has the same problem has Quanta computer, week 49, December 2019.

Please post that info here if you have the problem ONLY IF YOU HAVE THE PANIC.

At noon I got my brand new replacement from China. In the evening, I leave the MacBook to download music and photos. Couple of hours later, I return to find a message stating that the computer had to restart because of a problem.
The report sent to Apple Starts with: panic(cpu 0 caller 0xffffff8003491b2c): Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOGraphicsFamily. Thread 0x32f98.

I am beyond upset. Is this a hardware issue? My graphics card is an AMD Radeon Pro 5500M 8 GB.

 

[jpallarest]

I got only 2185 points for the iGPU GB5 Metal benchmark.
Does it mean I have faulty hardware? Can someone else post their scores here? Specially the ones who got a replacement already.

Same here, 2200 points on GB5, Metal, iGPU. Is this an issue?

The issue is system restarts and GPU Panic messages.

I personally feel the issue is Apple not fixing their terrible GPU performance in a machine that was released in November 2019!

I feel most sorry for the poor folks who bought uber expensive Mac Pro's still waiting for GPU drivers and the release of the MPX 5700 GPU. By the time Apple sorts themselves out the GPU's will be replaced by much better performing Navi2 and they'll be back to square one with the newer cards and terrible drivers.

I received a replacement MBP 16" yesterday. I CANNOT reproduce the error described above using Cyprian's method and the LG Ultrafine 5K screen. I'm on MacOS 10.15.4, though.

I did have a crash after plugging in external devices and attempting to wake the computer from sleep. If that's the only problem with this machine, I can work around it. Will report if there are other issues.

The Geekbench Metal Face Detection bug is definitely not fixed in 10.15.4. This is concerning.

I don't understand why there is still this (or these) unanswered questions:

• Does anyone with a 2019 15" MacBook Pro with any of the same processors used in the 16" models not encounter this bug? If so, why would only the 16" models be affected, assuming all 16"ers are as seems to be the case?
• Has anyone reached out to John Poole of Geekbench for his opinion? He would have access to all the Geekbench results in a way that is much easier to search than they let us do online.

It appears that Apple doesn't save the panic log report that it sends to Apple after a system restart, because I looked everywhere for it but couldn't find it. Maybe they do in another form (such as binary) or not in the format of the report they send to Apple. Either way, I couldn't find a log file that contained "Severity" even though I definitely encountered one such restart with a severity of 3.

First you need to see the panic. The ones with the anomaly are getting “Powerplay failed to resume” or “Powerplay failed to initialize”. It will happen when it wakes from sleep or if you run something that needs to switch to the AMD, like a game, Adobe Illustrator, etc. it will start intermittently and slowly progress to more consistently.

the Gerkbench 5 metal intel GPU test faithfully tickles the bug and if you have it, it will panic with the above panic message.

if you don’t have that issue, then you shouldn’t be concerned.

Thanks for all the information you have posted in this thread. I have an early MBP (purchased Dec 2019) and am encountering exactly the behavior you suggest-- a "PowerPlay failed to resume" kernel panic after waking from sleep. The issue was initially sporadic but now occurs every time my computer goes to sleep as you describe.

All Apple stores in my country (Germany) are currently closed and phone support was kind but clueless.

Should I expect my computer to roll over and die at some point? I'm trying to determine if I should push for a mail-in fox now and potentially wait months, or maybe buy a new machine in the interim and try to force Apple to take the earlier machine back. Or will my Mac keep working with this issue for another 1-2 months?

Attached is my kernel error. Curiously, I can run all parts of Geekbench just fine.

 

[TheJulianJES]

I’m also affected with a base model (i7. 5300M). Yesterday it was "only" when waking the pc up from sleep and now I’m unable to boot (only safe mode works), as it crashes through 3/4 of the loading bar.
Will probably just return it to Amazon, as I bought it just a couple of days ago and all Apple Stores are closed (Germany) (MBP manufactured in November).

 

[Loud2013]

Here is my story. I bought it Dec. 2019, works very well at the begining until Feb. I started buying some accesories type-C docker with HDMI and charging then it started to panic. At first the machine began to restart when sleep, but it can boot up normally.. Later the things went bad, when booting up the machine, it reboots again and again, the only way to boot up is go to the safe mode and restart. Because I didn`t have problems the first 2 months so I suspected it was software problem. So I clean all up and did os reinstall, but the reboot problem still exsited. I tried every ways from internet, the best way it to “pmset -a gpuswitch 1”, that was the only way to boot up at that time. But still the machine can’t not normally boot up(reboot several times and boot up by chance), I did worked with recommended kernel extension cleans(/Libaray/Extensions... and kextcache -I...) but not a chance to make it become a normal machine....until Catalina 10.15.4 came up, I was so happy and perceive it can be the fix of those kernel issues but NO! The machine can not boot up at all! Being restart endless....THen I tried last thing to roll back the Catalina 10.15.3 & 10.15.2....worst worst worst, the machine never boot up again...still endless reboot....I gave up Trying today, Brought it to Genious Bar, they said they will replace maybe the mainboard I don’t know.....left it there and wait for they call me what problem it is.
What a experience this is my first APPLE Laptop..... I used to be a windows user for over 20 years......and experienced Linux guys can not believe I can not solve the Linux base system....but I was wrong and gave up....good luck guys...

Don't tell me to disable the gpu, or turn this off, or uninstall that. Tell apple to fix their **** up.

Hi, insited.
Have you had any more issues with the latest MacBook Pro they sent you? My fourth will be coming next week and I'm really worried about having the same issues (restart, panic reports), again. The last one I got restarted three times within 24 hours.

 

[ha1o2surfer]

I wonder if apple is running the AMD GPU with too little voltage? the AMD GPUs they put in the 16" is like the Max-Q version video cards in nvidia laptops. They run SUPER low voltages, around .5-.6 under full load and the full fledge GPUs run up to 1.1v. Just rambling.

 

[TheJulianJES]

Not sure if this was the "cause", but I had my base model 16-inch a couple of days and it was working beautifully.
However, the first time I plugged it into my docking station (with two 1080p monitors) and it went to sleep, it crashed.
After that, it got worse over time and now I can't even boot into the OS setup (after reinstalling it) without safe mode.

For me, I believe my docking station broken my Macbook pro 16-inch because the first 2 months I used without any accessories, when I used docking station and happened to have panics, the panel above the keyboard was really hot, it was like the electric voltage unstable broke somewhere on the main board, still waiting for the fix from genius bar, it is definitely hardware problem I believe!

 

[TheJulianJES]

Apple just released "macOS Catalina 10.15.5 beta" for those who have access to the developer program (https://developer.apple.com/download/). (Waiting for a moderator to review this message because of this link, so it might already be out for a couple of hours)
I already returned my 16" MacBook Pro (because even Windows was crashing + macOS crashing at 2/3 of the "login"/"boot"-bar every time without safe mode), but maybe somebody else can test if the crashes are resolved.

I got my full replacement macbook pro 2019 16 inch 2 days ago. First thing I did was upgrade from 10.15.3 to 10.15.4...March 2020 build date. Unboxing it, there's a suction cap mark around the apple logo. Refurb. Apple are just sending us each others macbooks now.

It froze & restarted (CPU Panic) with hardly anything installed, while sleeping. Only power cable plugged in. No bluetooth devices connected. Latest T2 firmware as well. Everyone, return this machine. Apple have totally stuffed up here and aren't admitting it. They will happily move on to next model without addressing this issue.

I bought mine in November 2019 and out the box it had this issue. Multiple logicboard replacements with no fix, then finally a full replacement since the constant restarting diminished battery life greatly. Replacement the same. Now April 2020. 5 months of this.

Check out how coconutBattery reports two different manufacture dates, Apple are just reserializing & changing board build date as well. They aren't even trying to address the issue.

I've shut the macbook down and will be refunding now. No point even ignoring the issue, if it can degrade the battery on my original machine I'm sure this refurbished replacement won't even make it to 12 months without some sort of serious failure. Waste of time & $7000.

 

[30jafl1[3]

My replacement MBP 16" running 10.15.4 has been really stable since I received it about 6 days ago. On the day I received it, I did have one Bad Magic! crash plugging in externals while it was asleep, but that was the only issue I've had. I've been using it pretty much all day, everyday. It's constantly plugged into a monitor and other peripherals. I've done word processing, edited photos, watched YouTube, watched videos from external media, and played a game in Windows Bootcamp. I don't know whether the difference in stability is due to the change in hardware or the 10.15.4 software update, since I was running 10.15.3 on the original machine.

I haven't had any issue sever since I got rid of legacy and old 64 bit apps.. Dunno if it can help anyone.

Do you spot any in my minimal install list above? I began switching apps I use to 64bit in High Sierra ages ago.

I'd also like to note that this replacement machine, straight out the box with absolutely nothing installed froze & restarted. Nothing plugged in, no bluetooth connected. Literally couldn't do less with the machine. Then I installed the apps in my above screenshot with multiple freezes/restarts.

10.15.4 on my 2016 mbp 13" & 27" iMac 2015 with over 300 apps don't have any freezes & force restarts every other hour.

Catalina seems to have some 32bit libraries within the OS itself that apple haven't removed.

 

[Joeinger]

I haven't read the whole thread now, to be honest.
But I have problems with my mbp 16" while waking up.
Since the last macOS-Update it does not wake up properly, when a display is attached. I see a GPU-Panic everytime it goes to sleep several hours.

My wife got her machine last week, completely different software set, exact the same problem. We both have no problem with gpu-load until now. The last days I installed Windows on an external drive to play some games, no problem with windows os...

But both macbooks 16" (mine from december, hers relatively new, was delivered on monday) same problem with gpu-panics while waking up, when a display is attached.

Edit: Is there any scenario to reproduce the gpu-panic with load?

 

[insited]

Nope seems pretty random for me and from I read of others experience. The randomness is what makes the situation so frustrating, since according to murphy's law if you have important work on there it'll most likely restart when you walk away from the machine, but absolutely refuse to play up when on phone to apple support who will then turn around and blame you.

This is an issue with the Intel UHD iGPU on the Logic Board. I just had my entire logic board and touch ID board replaced since I was having the same issue. It did NOT fix the problem that I'm having.

 

[Loud2013]

Got back my MBP16", replaced mainboard, now working on Catalina 10.15.4, everything is smoking fast and no panic on sleep mode overnight, battery drain 8% a whole night and wake up normally. Not dare to plugin external display and accessories now I don't want to replace any parts anymore...

Just wait my friend...it will pop back up when you least expect it.

Luckily, according to Apple's support forums, they know of the issue and they're working on a software fix for the next Catalina update.
