Comment 6 for bug 987153

Hi Hansen,

No, my CPU is A8-3850 (no external video card, just the included HD 6550D). Also, I have to inform that after almost 7 hours idle the machine didn't crashed. I disabled power management (ie, left only the screen saver, but screen is never put to sleep).

Also, before the update to 12.04 turning off V-sync would cure the problem for me (also, avoiding fully preemptive kernel, ie: forced preemption enabled would cause a certain freeze). My kernel right now has voluntary preemption (one of the attempts to fix the problem was to use a custom kernel, right now I'm using a custom-built 3.2.16 kernel).

If the machine doesn't freeze for the rest of the day, I'll reboot and switch to Ubuntu kernel to test there too.

Ildefonso.
