<pre>Created <span class=""><a href="attachment.cgi?id=107584" name="attach_107584" title="Excerpt from /var/log/messages.">attachment 107584</a> <a href="attachment.cgi?id=107584&action=edit" title="Excerpt from /var/log/messages.">[details]</a></span>
Excerpt from /var/log/messages.
On a Fedora 19 box, (guessing:) since the update to
google-chrome-stable-38.0.2125.101-1.i386, opening YouTube videos causes the
screen to go blank. This also blanks all terminals ([Ctrl-Alt-F2] & Co.), so I
have to blindly log in and type "shutdown -r now" to reboot the machine.
When this occurs, /var/log/messages starts with:
| Oct 9 01:13:50 passepartout kernel: [ 431.004031] [drm] stuck on render
ring
| Oct 9 01:13:50 passepartout kernel: [ 431.004039] [drm] GPU crash dump
saved to /sys/class/drm/card0/error
| Oct 9 01:13:50 passepartout kernel: [ 431.004041] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
| Oct 9 01:13:50 passepartout kernel: [ 431.004043] [drm] Please file a _new_
bug report on bugs.freedesktop.org against DRI -> DRM/Intel
| Oct 9 01:13:50 passepartout kernel: [ 431.004045] [drm] drm/i915 developers
can then reassign to the right component if it's not a kernel issue.
| Oct 9 01:13:50 passepartout kernel: [ 431.004046] [drm] The gpu crash dump
is required to analyze gpu hangs, so please always attach it.
| Oct 9 01:13:51 passepartout kernel: [ 431.508040] [drm:i915_reset] *ERROR*
Failed to reset chip: -110
| Oct 9 01:13:55 passepartout kernel: [ 435.733338] Watchdog[2408]: segfault
at 0 ip b6387197 sp afd6fdd0 error 6 in chrome[b257e000+51ab000]
| Oct 9 01:14:00 passepartout kernel: [ 441.006052]
[drm:i915_gem_wait_for_error] *ERROR* Timed out waiting for the gpu reset to
complete
| Oct 9 01:14:01 passepartout kernel: [ 441.326032]
[drm:i915_gem_wait_for_error] *ERROR* Timed out waiting for the gpu reset to
complete
| Oct 9 01:14:01 passepartout kernel: [ 441.377037] [drm] GMBUS [i915 gmbus
vga] timed out, falling back to bit banging on pin 2
| [...]
(For the complete log cf. attachment.)
*After* the reboot /sys/class/drm/card0/error reads "no error state collected",
so if you need this file, please state so as then I'll have to set up a script
to copy it somewhere (because all the screens are blank so I can't do that
interactively).</pre>
