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,

adamw

you should as you are finding always keep a bootable backup before updating.

there are 3rd party driver issues (there have always been such issues with every update btw)

5970? maybe there is a suspect.

Two sites that I follow that tend to get a lot of reader feedback and reports on OS issues:

MacFixit

MacInTouch

With just one display attached, via DVI direct to the Radeon 5870, I still get this problem

ATICLASS::detectPowerDown: GPU is not found. PCI config access fails. VendorID = 0xFFFF !!!

Let's hope 10.8.4 addresses this?

I think your card may be failing. Instead of going to sleep, it drops out entirely.

To make progress, you should substitute a know-good card. Your local genius Bar may be able to arrange to have one on hand. Your Appointment for an evaluation is free, in warranty or out.

Hi everybody,

I never posted here but often read about issues !

Exact same problem here, with the same mac pro 2008 and two displays connected with mini display port throught a 5870.

Starting this morning, the screen keep on turning to black. Impossible to access the mac throught the network.

Need to reboot each time.

What was the diagnostic for your problem ? The fact is, that this kind of problem always occurs when you don't "need" them ! Lot of work... not enough time... and problems...

Thanks

If one display drops out, Apple suggests using the Detect Displays button. They also suggest you can sleep, then wake your Mac to issue the Detect Displays identification sequence.
