Hello, I’m encountering a very similar bug on a completely different page!

It’s a marketplace list page which has many small paused videos as a thumbnail. They seem to leak the ram like crazy as I scroll down and my 14inch MBPro (10/16/16) freezes and reboots after 2-3 minutes. The crash reports indicates a watchdog error.

I have updated to the 12.1 Beta to see if they fixed it and just like @jbarronsd, now it doesn’t reboot but kicks the fan at full speed until I give up and force shutdown.

I can replicate this bug on Firefox, Chrome, Brave, Safari in safe mode too. I even try two fresh installs and same bug.

I can’t replicate this on 12.0.1 Macbook Air M1, Macbook Pro/Air intel


At least, I am somewhat relieved I’m not alone and hopefully this is a software issue. I tested my RAM by running intense 3D tabs on Safari and could reach high levels of swap memory without crash.

(Also all diagnosis haven’t returned any hardware issues)
 
This happened to me today… just received my MBP today and it crashed while viewing HDR content. Glad it’s being fixed in the beta.
 
The only advice from me is. If your machine crashed. When it asked to send a report. Send it. More people sending reports prob means higher priority
 
Had a call with a senior advisor today to figure out the cause together but lost some time as I’m obliged to downgrade from the beta to 12.0.1 for them to start monitoring.

Finally managed to downgrade and now waiting for another call.

I’ll keep you guys updated in this thread if get any news.

In the meantime it would really help out if someone with similar specs could test the page that crashes my mac 100% of the time (as it would allow me to confirm this is probably software and not hardware)

On 16 MBP M1 max with 32gb ram, the page lags but doesn't crash the OS.

same thing here. I can get it to crash every single time now in HDR 4k video window mode while scrolling. With the plug in, it just disables my HDR on chrome and no problems when there's no HDR... I'm on 16 Max

Thanks a lot for testing, that’s the behavior I get on my other macs and what I would expect from this poorly optimized page.

(Weirdly though, when I try recreating the HDR youtube crash, I can’t)

I have since sent a long sysdiagnose to Apple’s engineering team through a support advisor and should get an answer maybe next week. Hopefully they find the cause wether it’s software or hardware.
 
Update: just got out of the Apple Store and froze + crashed every single M1 Pro laptop I put my hands on ( 4 x 16” and 2 x 14”) with the website. Just had to let them load more and more thumnail videos…

I tried this on mine and although it did not crash, I was watching Activity Monitor and saw a huge spike in memory consumption as the pressure quickly built up...I closed the tab before it got too severe so this seems like another memory leak point in Monterey.

Guess when I was looking at that website :)

12.1 beta, same issue as what cababah posted, it went up to 64 gb and started using swap, didn't crash but not good!

Yup, when it starts getting orange, the next spike causes the crashes!
Worth noting that all the MBP in the Apple Store had 16GB Ram, and so does mine. I’m guessing 32/64 have more leeway to survive the ram increase spikes.

At least I’m reassured that this seems to be a software issue and not something hardware exclusive to my MBP. I’ll send more info to the apple support and hopefully they get this sorted in next release.

The 32/64GB ones will survive a little while longer but this is one of many reported memory leak issues in Monterey...really hope this gets fixed soon as it is crippling otherwise amazing hardware.

I have another 15" MBP (Intel) on 12.1 and I tried the same page and it really hangs up the computer but I don't see the massive memory leak that I was seeing on my 14" (M1) on 12.0.1. I think it's just a combination of Monterey teething pains and a very poorly designed website.

Howdy,

I keep getting a kernel crash when watching HDR videos in Youtube and scrolling through the comments - here is an example of one:

Is anyone else having this problem? I wonder if it is hardware related in which case I may need to return it but I have been able to reproduce it a few times in a row and the entire machine will reboot each time. No bueno...

Just to add - this happens when scrolling up and down rapidly through the comments but only seems to happen on HDR videos.
Was YouTube limiting you to 2160P@60 HDR on your 14" MBP. I am conducting looking at it on a M1 24" iMac with up down scrolling when playing video but I am on 12.1 beta.
 
Here's an earlier post I made in a different thread. Hopefully, this can shed some more light on the issue.

I am not an expert by any means, but this is my best guess as to what's happening:

> panic(cpu 0 caller 0xfffffe0024033d68): DCP PANIC - IOMFB int_handler_gated: failure: axi_rd_err [0x40300034]
- iomfb_driver(8)

The panic is being reported on CPU 0 (the first CPU), which is one of the efficiency cores.

This appears to be a fatal crash in the display coprocessor, or DCP. It has something to do with IOMobileFrameBuffer, which is used to manage the screen's framebuffer. (source: https://iphonedev.wiki/index.php/IOMobileFramebuffer)

I think "int_handler_gated" refers to an interrupt handler.

> RTKit-1826.40.9.debug - Client: local-t600xdcp.release

"RTKit" is Apple's custom real-time OS used on many of the coprocessors embedded in Apple silicon chips. The DCP is one of those coprocessors. (source: https://asahilinux.org/2021/08/progress-report-august-2021/)
What's interesting is that the version reported here appears to be a debug version.

"t600x" refers to the CPU model number for the new M1 Pro/Max Macs: M1 Pro is T6000, and M1 Max is T6001. (M1 is T8103.)

tl;dr The display coprocessor crashed.
 
I'm not having any issues playing the video you posted at 4k HDR 60 fps, but I'll keep experimenting over the next few days to check if I run into anything. Haven't experienced any crashes or weirdness so far.
 
I'm finding scrolling (14" M1Max 24GPU) to be bruuuuuuuuuuuutally choppy and slow since updating this morning.
Just basic forum scrolling. My 11 year old MBP is smoother.
Restarted and its still there.

Did you try play the video is the default viewer and quickly scrolling through the comments section? I don't think anyone is having problems with playing videos, just the combination of movement and playing HDR video somehow causes the crash

To clarify, there are a series of specific actions that are causing it to happen to those of us affected. Can you try the following exact steps as outlined by the OP and let us know your experience? Here are the steps:
1. Play HDR video in Youtube
2. Make video full screen
3. Reduce back to smaller size to view comments
4. Scroll up and down through comments varying scroll speed
5. Repeat 2-4 and it usually will eventually lock up and the machine will restart
 
Well this is interesting. I just updated to 12.0.1 and I cannot get the crash to happen anymore. So far I've been only testing in Safari and will try more later along with testing in Chrome. My model is the 16" Max with 32GB and 1TB HD.
 
I have the exact same issue, frozen and reboot each time I watch HDR on YouTube or other sites, besides, when I am downloading multiple games from Apple Arcade while browsing, it also crashes too, can be replicated even in safe mode.

Thank you my m1 pro just crashed another round today?

That's good! But in my experience, Safari was the easiest to crash out of all the browsers. It can sometimes crash it instantly when playing an HDR video and I scroll down just a tiny bit, lol
