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

yeah, i admit my returning it was more a matter of principal than anything else.

(i paid $3k for this machine, it better work flawlessly, demmit!!!)

but i plan on keeping the exchange 'cause like i mentioned, it's not really too much of a hassle, and if it's true that they're all doing it.....

meh. wait and see. i'd rather have it this way than to go back to being without my octomas prime.... :D
 
I am a "back to the flock" user, after 15 years of freaking PCs for CAD/Animation/Video work.

I have had my MP 2.8 Octo running since last Saturday. I have not had this problem (OR ANY OTHERS, knock on silicon), but I don't have any extra RAM or Drives installed - or Boot Camp. Of, course, as another user mentioned, it takes like 15 -20 second to reboot (AMAZING), so I may not have noticed it?

I have dealt with PC issues (include building them for ten years) and this type of problem is not really a huge deal, COMPARED TO OTHER PROBLEMS I HAVE SEEN - see, I don't want to piss any one off - cause I have been there stuck in the techsupport loop - I am just saying, this could be a lot worse.

I learned years ago, that if there is a simple fix - no matter how badly you want something to work (the way its supposed to) its better just to fix it the best you can and get back to work, than spend six hours on the phone yelling at people (not that that is really the issue here since Apple seems to be aware of this).

Kudos to anyone that has stuck it out to get a replacement! But is that helping?

If you turn off Sleep Mode - it stops doing this right?

I am doing that as we speak just in case, until I hear this issue has been resovled via update.

I agree. They are definitely aware of the problem. It will be solved eventually if not sooner. The other 99.9% of my MP works beautifully so I can wait.
 
Boo :( After 2 or 3 weeks of perfect operation, my new Mac Pro rebooted upon waking from sleep. My hibernatemode is still 0, so I guess that blows my theory.
 
Ack! same here!
my pro was sleeping/waking fine for 2 weeks solid every day two or three times a day.
slept this morning, and rebooted on wake ffs.

I think someone somewhere has a switch to enable the fault!!!
 
My latest theory is that it is Boot Camp. The little "restart in Mac OS X" thing that gets added to the Windows task bar writes bad values to the PRAM.
 
oh, now I am going to put your theory to the test, as it just hit me, I have just installed bootcamp XP on my Pro to play Tiberium Wars in XP and its since this that it has rebooted 3 out of 4 sleeps.

Going to remove it right now!

that would seem odd since it sleeps fine when booted into windows.....
 
I just went put my computer on stand by while in windows (internal in bay 2) and came back an hour later and noticed that my computer had rebooted.

crap, that sucks. i haven't had it happen in windows yet at all. guess i'll have to do more testing.....:eek::(
 
My Mac Pro is set to never sleep - so I never knew if mine had this issue or not, until today. I inadvertently set mine to sleep, and when I woke it up it rebooted.

Not a big deal for me as I don't want mine to sleep - but if it does turn out to be a hardware issue that cannot be fixed with software/firmware then I'll get mine replaced in due course.

I'll keep watching to see what happens.
 
I want to chime in with my experience on this. I had zero issues with this for several weeks. I left it on to sleep over night and for hours during the day. I installed OWC ram, and nothing ad happened as a result. It never even thought of restarting from sleep. One night a few days ago I needed to reinstall OSX on the same drive. The next morning...guess what. Rebooted from sleep.

This discussion can become one about the chicken or the egg. Software runs on hardware, and both are reliant on the other to function properly.

I can say on my end, it seemed to be purely a software issue that disturbs the functionality of the hardware. I know this is a lot of money to spend on a machine, but does anyone out there think something this complex will be flawless?! I don't think perfect is possible.
 
One more brand new Mac Pro to report on that issue if that makes any difference.

8 cores, 2.8 GHz, 4 Gb of RAM.

I thought I was doing something wrong with sleep mode until it happened a second time and I browsed the forum for similar experiences.

I guess I will do without Sleep mode for the time being.

Other than that, after a smooth migration from Windows and week of use, it is easily the best computer I ever had.
 
ATI Radeon HD 2600 XT Firmware Update

Now in software update.

This update is for Mac Pro computers with one or more ATI Radeon HD 2600 XT graphics cards installed, running Mac OS X 10.5.2 or later with the Leopard Graphics Update.

It updates the ATI Radeon HD 2600 XT graphics card firmware on all of the ATI Radeon HD 2600 XT graphics cards in the Mac Pro to improve system stability.

Installing this update on a 2.8 GHz Mac Pro system configured with multiple hard drives or more than 2GB of RAM will result in the system meeting Energy Star 3.0 requirements.


Any improvement?
 
well, i've had one successful sleep so far....

hopefully this will solve my kernal panic caused by a firewire device problem also.....

I agree, when I was running an Imac 2.8 and i cloned the drive in to my Mac Pro i had no isues for weeks and weeks, slept lots of times. I reinstalled Leopard using archive and install and I had sleep reboot issues immediately!

Just an update, this has nothing to do with having a bootcamp partition either as I have removed that.

Hope Apple do know about the issue and fix it fast. I love waking up in the morning and my Pro waking in a few seconds as oppose to booting up in a few minutes (it seems that long).
 
Heh just looking at the Poll figures again....I wonder out of all of those that said they have no issues have recently found out they have this fault also!?

Shame people cant retract and reassign their vote.

Same here, every time I plug in my Firebox I get a kernel panic.. Strange and annoying, I have to shut down to plug it in every time I'm making music..

strangely enough, this problem seems to be fixed. is it working for you?

I installed this "firmware" update but system_profiler is not showing a difference in the firmware or EFI revision numbers:

10.5.2 + Leopard Graphics Update Values:
Chipset Model: ATI Radeon HD 2600
Revision ID: 0x0000
ROM Revision: 113-B1480A-236
EFI Driver Version: 01.00.236

10.5.2 + Leopard Graphcs Update + ATI Radeon HD 2600 XT Firmware Update
Chipset Model: ATI Radeon HD 2600
Revision ID: 0x0000
ROM Revision: 113-B1480A-236
EFI Driver Version: 01.00.236


Can anyone else verify that the ROM Revision & EFI Driver versions didn't changed? Sounds like this is more of a driver update than a firmware update or I just need to find out how to get the firmware version from the card...
 
After weeks of having other problems, but not this one. Now she reboots instead of coming out of sleep mode.

I have a 2.8 octo/10GB/8800 w/ stock 500GB and an F1 1GB. I've been running this configuration since day one, w/o having an issue.

I did notice this started happening last night after transferring hours of video between my camera and workstation. I used the front firewire port and left the cable connected after I removed my video cameras.

I used to not have anything plugged in the front until a few days ago. Last week I was plagued by stuff not working and having to reboot to fix it. My gut has a bad feeling about having parallels working through boot camp. I already limit my use of windows xp through parallels because it made my superdrives and programs I was importing/exporting from buggy. A reboot and no winbloze fixes that... but I hate having to reboot in 10.5. Shouldn't ever have to!
 
I did a little experiment - pulled the firewire cable out of the front and haven't had the reboot after sleep problem. 2 successful sleeps now.
