Leopard reboots-on-wake if Parallels has been run before sleeping

I have Parallels Desktop 3.0 (5584) installed on a clean 8 core Mac Pro 'early 2008' 10.5.2 system running an XP Pro VM.

If I run Parallels at all - just 'boot' XP, log off, then quit Parallels - then when the Mac Pro goes to sleep, it reboots instead of waking up when I touch a key. I've tested this over and over again and it is 100% consistent:

If, after a reboot, I run various OS X apps and let the machine sleep, it wakes fine.

The problem is only if I run Parallels after a reboot - then I cannot wake from sleep.

I've reset SMC and PRAM, repaired disk, permissions, run onyX to clear caches and logs, etc. No change. I have three bootable system partitions from when AppleCare told me to do a clean reinstall of 10.5.2. I've spent weeks on this...

1. One partition is the clean 10.5.2 with my user account migrated. Zero problems ever with this partition - sleeps, wakes, etc.

2. Another partition is a clone of 1 (carbon copy cloner) with Parallels Desktop 3.0 installed.

3. The partition I've been running from for several days is a clone of (1) but with Fusion 1.1.1 and the VM was converted by the Fusion converter from the Parallels VM. This has exactly the same consistent behavior: if Fusion is run during a session, then the computer will reboot instead of wake from sleep. If Fusion is not run, then everything is fine.

Because this reboot-on-wake situation (reported in various other Leopard chat lists) only happens if Fusion or Parallels is run, it seems to be some kind of interaction bug between what is required to run a VM and Leopard. The question is: is this a bug in Parallels? (and Fusion?) or is this an Apple bug?

In an Apple chat list, someone reported having this problem after running Aperture. So, it seems like this is an Apple bug that is exposed by these various programs.

I see no other reports of this behavior in these Fusion or Parallels forums. Is anyone else seeing this reboot on wake issue here?

Any ideas for getting a stable system, short of never letting the computer sleep?

Thanks!

Hi all,

Just wanted to report that this reboot-on-wake issue has been resolved by Apple with the release of a firmware update on 27 March for the Early 2008 Mac Pro. 6 weeks of diagnosing and workaround around this issue is happily at an end!

Cheers,
Karl
