Title:
  system crashes randomly, needing hard reboot

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Randomly, but very frequently (once or twice per hour), the system
  freezes, crashes, then needing a hard reboot.

  After rebooting, the last lines before crash in logs are ALWAYS some of the following:
  "Skipping EDID probe due to cached edid"
  "EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro,commit=0"
  "EXT4-fs (sda7): re-mounted. Opts: commit=0"

  And some times some of the following as well:
  "padlock: VIA PadLock not detected."
  "EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts: (null)"

  Also, this bug never occurred in this hardware before, with Xubuntu 10.04, but quite often now with Ubuntu 10.10.
  At first I though it was linked to a pulseaudio issue, not yet solved : https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/629339
  So I posted a question as well for the pulseaudio issue : https://answers.launchpad.net/ubuntu/+question/132340

  But now it seems that bug occurs as well when no sound is played at
  all, and when pulseaudio seems to be fine.
