Do any of you have the "restart on power failure" setting in Energy Saver?
I don't.
I've changed Energy Saver settings to allow the monitors and hard drives to sleep, but not the processor, and thus far, no more surprise reboots.
I've not yet installed virtualization software (haven't decided yet between VMWare and Parallels), but my guess is this problem could really mess up a virtualized Windows installation. -
Jan 26, 2008 6:37 AM in response to JimRobertsonby The hatter,I've read about problems with Energy Saver, but didn't realize there is now an option (again, from G5 days?) for processors.
Something like "automatic, high, reduced" setting, AND some kind of sleep setting?
I've seen some threads on Parallels that would keep me away for now, and I'd wait for Fusion 1.2 or whatever. And how to fix it w/ firmware and OS patches? -
Jan 26, 2008 6:47 AM in response to The hatterby JimRobertson,I should have been more precise. The options are to sleep the whole computer (including processors and cards), the hard drives, or just the screen. So, there's not reduced power consumption setting for the processors independent of anything else.
As far as how this will get fixed? Who knows. I certainly HOPE it doesn't mean a new motherboard! My guess is that it's some software glitch that might get fixed in 10.5.2, or perhaps a machine-specific update... -
Jan 26, 2008 2:55 PM in response to transplant6by Tim3308,Hey hey hey, count me in too. Brand new 3.O gHz, reboots upon hitting the keyboard after several hours asleep. Gonna try the advice given here. -
Jan 26, 2008 3:37 PM in response to transplant6by jesterdev,netdog from the Mac Rumors forums suggests running this: FSCK -fy
in the console. Says that fixed the problem.

Jan 26, 2008 3:42 PM in response to jesterdevby The hatter,You should always run FSCK after a hard restart, not to cure the issue with Mac Pro, but because of potential damage to the drive's directory.
And not from the terminal, but from single user mode command line. -
Jan 26, 2008 3:47 PM in response to The hatterby Danman87,Count me in. I have the same problem with the 2.8
I reset the PRAM and it seemed to fix the problem. Then a week later it happened again. This time I reset the SMC and PRAM and so far it has been sleeping just fine.
I hope all that is needed is a software/firmware update. -
Jan 27, 2008 4:58 AM in response to transplant6by Trickartt,May as well add me to the list too- maybe with enough noise, Apple will offer a proper fix for the problem?
Again, I have brand new Mac Pro 2.8x8 with the same problem. I did the PRAM and SMC resets which seems to have fixed it for the time being, but I'd rather a proper fix than to have it happen again- unplugging everything is such an unnecessary inconvenience! -
Jan 27, 2008 5:21 AM in response to transplant6by Craquehead,I'll just chime in to say that I have started experiencing this, right after adding 8GB of 3rd party memory. I'll try the PRAM and SMC resets and see if that fixes it. -
Jan 27, 2008 7:37 AM in response to Craqueheadby The hatter,Also try with just the 3rd party memory.
Could you mention where / what it is? -
Jan 27, 2008 2:37 PM in response to transplant6by Redux,I have the same problem with MacPro 2.8 2x quadcore early 2008. When I wake up from sleep the MP reboots. I have only 2 Gb original RAM. An external FireWire HD (chip Oxford) is always connected to the MacPro. Power supply from an UPS.

Jan 27, 2008 9:26 PM in response to transplant6by phjo,I thought my mac pro (8-core 2.8) was not prone to reboot by itself when awaken, but it did it today for the first time after a night of sleep...

Jan 27, 2008 9:43 PM in response to phjoby cawu,Darn. I thought this wouldn't be a problem for myself, either, but my MP just did it for the first time a little while ago - also after an overnight sleep.
My MP has also been turning itself on every 24 hours at 4pm, but that's a totally separate (or is it?) issue...

Jan 27, 2008 10:55 PM in response to transplant6by bugblatter,Same Problem here, new MP 8 core 2,8 lots of firewire and usb stuff. NO additional RAM or other internal upgrades.
Reboots every time he was asleep over night.
I tried resetting the SMC and the PRAM, nothing works for me
I hope Apple will fix this soon! -
Jan 28, 2008 6:47 AM in response to transplant6by bkick,Oh, i´m not alone, nice to hear!
2,8 ghz, 2xquad. same problem. restarts after not working some hours.
my mac pro has just the built in RAM, no separate raid or something else.
