Problems with kernel panics when sleeping since 10.6.8
Hi folks,
I installed 10.6.8 the day it was issued, and since then have had some very odd problems with sleeping my Mac Pro. Intermittently, it goes into a half-sleep state when I request sleep mode; the fans still spin, but the sleep light pulses. It refuses to wake up, requiring a hard reset. The console logs show:
Sleep: Drivers Failure Panic
The specific panic is:
panic(cpu X caller 0xffffff80002251fb): "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts, unresponsive CPU bitmap: 0x101, NMIPI acks: orig: 0x0, now: 0x0"@/SourceCache/xnu/xnu-1504.15.3/osfmk/x86_64/pmap.c:2741
where cpu X varies between any one of the 6 cores.
So far, I've tried
- Resetting the PRAM and SMC
- Disabling a raft of sleep related options (Wake on Bluetooth, etc)
- Reinstalling the 10.6.8 update via the Combo updater
- Repairing disk permissions
- Reinstalling from the factory DVD and re-running the combo updater
And no doubt other things I've forgotten. The only thing that seems to fix it is to not install 10.6.8; when I reinstalled 10.6.4 (the factory OS), it slept and woke fine 10 times. As soon as the combo update was installed, it started sleep crashing again after 4-5 attempts.
I'm assuming this is some rogue driver bug introduced in the .8 release, but I've not seen anyone else suffering the problem. I would roll back onto .7, but will obviously need .8 to install Lion when it arrives.
Does anyone have any suggestions that I've missed, or has anyone else seen this problem?
Thanks,
