My Penryn Mac Pro has spontaneously rebooted upon waking...

Mine didn't do it when I got it - sometime over the last 2 or 3 days it's started to do it consistently every sleep.

A quick PRAM reset seems to have fixed the issue for now.

Give that a try and see if it helps anyone else who has the issue.

did that. didn't help.
 
I'm experiencing this problem and it sucks to say the least. I will not be pleased if this is a hardware issue as I've waited 3+ years for this baby:

Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 3.2 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 10 GB
Bus Speed: 1.6 GHz
Boot ROM Version: MP31.006C.B02
SMC Version: 1.25f4

2x 150gig Raptors RAID-0 (boot)
1x 320gig Seagate (standard, timemachine)
 
I've never had it happen with my 1.5 week old Mac Pro (2x2.8, 320, 6 gb ram). I let it sleep to the default settings. My previous Mac, B&W G3, which I used for 9 years or so, I never put to sleep. So, I'm wondering when I'll change the setting on this baby. I had one freeze which I had to force a shutdown and so far that's my only glitch. I'm not sure I caused that by uplugging some usbs and an ethernet port.

I just called to Applestore and arranged returning. TNT will pick old one away and they send me new one. My PSU makes sometimes weird noise and this baby is rebooting after sleeping sometimes. Just call Apple and require a working machine! We don´t pay +2500€ for this kind of metal crap. With 2500€ I want a machine that works. Guy in Applestore said that it might be a problem with power supply. He didn´t really know what it was all about.

Well I got a new machine, hope that´ll work fine. I feel kinda bad about Apple, I´m pain in the ass to them. But I´m not so rich mother f*cker that I could go and buy a new one or live with faulty one. Don´t hit me because of that :(
 
I doubt its a problem with the power supply, since several folks have stated that they can sleep the Mac Pro just fine under Windows (bootcamp). All signs point to a problem with Leopard. If you've got a Macbook/Pro, chances are you have wireless problems. If you have a Mac Pro, the reboot after sleep is pretty much guaranteed.
 
I hope it's software. I just don't have the time to return this machine. It would take weeks to get a new one. It seems like this is a software issue to me.
 
Applecare is willing to do a replacement if this still continues after the SMC, PRAM resets, & clean OSX install prove to not fix the issue.

There was no discussion regarding refund.

Replacing the logic board was mentioned as a possible solution.


After performing the SMC & PRAM resets, problem seems to have gone away...only time will tell for how long.
 
It seems that the problem with rebooting after sleep has happened to quite a few people. Mine did it a couple of times, but hasn't since. I was wondering if we have the same Boot Rom Version. Mine is MP31.006C.B02.
 
I just called to Applestore [...] He didn´t really know what it was all about...
I find it hard to believe that no Apple telephone operators seem to have heard about this problem. I haven't even received my Mac Pro yet, but I'm having shipping issues so I've called Apple twice and each time, as an aside, mentioned my concerns about this alleged rebooting problem -- twice the rep seemed "conspicuously" clueless. I am somewhat of a conspiracy theorist, but it's almost as if Apple telephone reps are instructed to play dumb to make us feel like we're the only one with a given problem. Then again, maybe that's just basic corporate business etiquette.
 
Click on the apple icon at the top of the screen, About This MAC, and then more info. You'll see the Boot ROM Version listed there. I was just curious as to how many people with that particular version are having the sleep issue.

Yes, mine is also MP31.006C.B02

I have reset PRAM and also done the SMC thing, and not fixed...
 
I finally bit the big one and called Apple.

I talked to a really nice guy named Jason. I told him that I went to the support forums at apple.com and saw that many other people were having this problem. I told him that I reset the SMC controller and zapped the PRAM, which was advice given on those forums. He said that he had heard about this from a few other people, and then had me move my PowerManagement.plist file to the desktop, and recommended that I uncheck the "Put the hard disks to sleep when possible" box. He said that he solved a few people's problems that way.

He went on to say that he thought this was a software problem that would be fixed very soon with an update from Apple. If this problem continues I am probably going to call back and ask for a replacement. He gave me a case number so I didn't have to go through all this again when (and if) I call back.

Except for the sleep issue, I am extremely pleased with this computer (and ACD). It is the nicest, fastest computer I have ever used or owned and it seems a shame that something as trivial as sleep doesn't work reliably.

I don't know if I will sleep my machine anymore. If I do, I will likely boot from the Macintosh HD (currently I am using a 750GB Samsung as my boot drive and a 1TB Samsung as my TM drive) because I am a bit worried about having data lost because of this silly problem.

I recommend that if you are reading this thread and are having the same problem, that you at least call Apple and make them aware of the issue. The more people who call, likely the faster this issue will be ironed out. The phone number for Applecare support in North America is 1-800-275-2273.

that's what they had me do too, didn't help.

i think i'm gonna call back tomorrow and arrange an exchange. i also hope it's a software issue that'll be fixed, but am not willing to take the risk on a $3k computer.

i'd think apple has a lot of tech's and pro machine users would be in the minority as far as the mac community goes, so it seems like there'd be a good chance that they wouldn't have necessarily heard about this stuff....

Mine does it as well. I figure there is a software fix eventually. I'm not going to exchange mine over this. Everything else works just fine and I feel that the chance of ending up with the same problem in another machine or worse, other issues that could be really bad is definitely not worth the risk. It's not that big a deal. With the super fast boot time, I don't mind turning the thing off. Seems like I've always had wake from sleep issues with past Macs. It just doesn't bother me like other folks, I guess.

As for the aforementioned chance of a power surge, in 24 years of owning Macs (and a pc or two) I've never, ever, had a power surge of any kind damage a computer. That's what surge protectors are designed to protect. In any case, I have it on a high end UPS/conditioner/surge protector.

While I'm not especially pleased, as long as I can sleep at night, I don't really care if the MP doesn't. Or if it ever does. So long as the damn thing starts up in the morning and runs ok, I'm happy.

I'm with you. I spent a lot of time stressing over this and complaining in other posts, but now that my MP is due to be delivered tomorrow (and I have no control over whether it will have the problems) I have let go. Like you said, if you return over a sleep issue, your replacement machine could have worse problems which would suck. And, I would think Apple will address this at some point with a software / firmware update.
 
I responded to Kirk's query in another thread and said that my MP had never rebooted after sleep . . . and then it did! I zapped the PRAM and also reset the SMC (as suggested) and it went away.

I feel the same as, well, just about everyone. While on the one hand, I hate the fact that it has this glitch (after spending that much), I also feel like it's probably a software issue (since sleeping in Windows seems to be OK), or at the worst a firmware problem.

I'll call Apple later today myself to report it and get a problem number.

There's a part of me, though, that isn't planning on letting it sleep all that much. As has been mentioned, it boots SO fast (I use a 1TB Samsung, takes less than 20 seconds from doing to desktop) . . . and it also seems to me that, well, rebooting cures some stuff, so if for now I have to reboot in the morning, that's just fine with me.

I just spoke with AppleCare, and they are very aware of the issue, and the agent said they are working to fix it. I'm going to be patient and not worry about it, as this is the only thing about this machine that is not perfect IMHO.....
 
question:

why put it to sleep?
why not just 'shut down' at night, and then boot up in the morning?
power savings? how significant is that?

If you need access to your computer while your at someone's house, or at work, you can leave the machine in standby. So leave it on, and asleep so that you can access it if you ever need to. (Back to my Mac or logmein.com)

I feel as you do. I haven't called Apple yet because the problem only occurred a couple of times. I usually put it to sleep during the day and shut it down at night. I just can't see replacing the machine unless the problem persists and gets worse.
