[Bug 593045] Re: Graphics output flashes repeating colored patterns

[Andrew]

Syslog during a crash

** Attachment added: "syslog"
   http://launchpadlibrarian.net/50213416/syslog

** Description changed:

  Occasionally, maybe once a day, a video crash happens at random - the
  screen goes blank and then repeatedly flashes colored stripe patterns.
  When this happens the system still responds to pings, and if I mash
  Ctrl+Alt+F2 enough the text login prompt can be seen for a split second
  between the flashing stripe patterns. So this looks like a problem only
  with the output to the monitor; the rest of the system appears to be
  responsive, and the problem is not limited to the X display.
  
  Syslog during a crash contains items such as:
  
  anacron[749]: Job `cron.daily' started
  anacron[1424]: Updated timestamp for job `cron.daily' to 2010-06-12
  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
  render error detected, EIR: 0x00000000
  [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 4077 at 4076)
  [drm:i915_gem_idle] *ERROR* hardware wedged
  [drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck
  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

  [drm:i915_gem_idle] *ERROR* hardware wedged
  
  I don't know whether the cron jobs starting was just a coincidence. I
- tried running manually running every script in /etc/cron.daily but was
- unable to reproduce the crash.
