Comment 31 for bug 610055

I'm getting somewhat similar crashes on my HP 6730b with Intel GMA graphics. Crashes don't occur as often and I can safely say that they happen on AC or battery power. I might go a couple of days (realistically two - three max) without a hang.

2. This is a /var/etc/messages snippet of a crash that occured on AC power, while I was away from keyboard (nothing special was running, only Chromium, VIM and Evolution).

If somebody wants a complete log set - I'll upload it per your request. I feel that this error is somehow related to the ACPI - especially as it happens more often as I try to standby the system, or return from a standby.
