Kernel log of two repeated hangs, the last part of the kernel log before the
first hang and the entirety of the log before the second hang
Using vanilla Linux 3.14, X server 1.12.4 and Intel driver 2.21.15 and GNOME 3
on a G43 chipset, I get random lockups of the X desktop. The mouse cursor
moves but the rest of X is dead; nothing responds. I can switch to the console
(in order to reboot the computer) but if I switch back to X then the machine
will hard lock within a short period. After switching to the console, after a
short delay the kernel will report:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring
idle
This definitely happens a lot while composing emails in Evolution (and is
therefore EXTREMELY ANNOYING :-). I get the feeling it may happen some time
after having dragged a window to a side edge of the screen to half-maximise it.
The lockups seem to happen in clumps. That is, for weeks the machine will be
stable with no problems but then there will be one lockup followed by another
lockup, sometimes within minutes of rebooting, and sometimes repeating a number
of times, eventually ending by my giving up using the computer.</pre>
