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. Besides problems with random hangs, I do have problems with standby - sometimes computer successfully goes into standby, sometimes it just hangs and waits there. The same occurs sometimes when booting up the computer. Logs look unproblematic, but they do share a common theme:
1. I'm getting the same problems when I disconnect my power cable (actually only noticed that this is related due to Jan 3 10:54:23 luka-laptop-hp kernel: [ 1504.739292] EXT4-fs (sda6): re-mounted.

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).

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/610055 Title: [pm-utils][maverick] system stutters, freezes, hangs, gratuitous 'Commit=0' errors -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
