Public bug reported:
Binary package hint: xserver-xorg-video-intel
After a recent upgrade to Lucid, I get intermittent Xserver crashes resulting
from a few days of uptime. Usually it happens when power-manager kicks in to
blank the screen. I get these message in the kern.log:
Jun 13 01:21:22 domus kernel: [392077.221266] [drm:i915_hangcheck_elapsed]
=*ERROR* Hangcheck timer elapsed... GPU hung
Jun 13 01:21:22 domus kernel: [392077.221276] render error detected, EIR:
0=x00000000
Jun 13 01:21:22 domus kernel: [392077.221293] [drm:i915_do_wait_request]
*E=RROR* i915_do_wait_request returns -5 (awaiting 18764775 at 18764774)
Kernel seems to be intact: other services, like webserver works. I get a
messages that a low graphics mode should be eneabled. And the dri/drm
capablipities are being lost, unless I reboot the machine.
The messages similar to the above are related to a few other issues however not
identical to the one I experience.
This olso maybe related to the i915 memeory handling, 'cause I can see that
memory gets "more abused" on Lucid (I also witness it on an ATI chip). Is there
a memory leak in the Xserver code? I see "(II) intel(0): No memory allocations'
in the Xorg.log. Moreover,
Along with the kern.log messages I see the following in my
Xorg.[012].log:
Xorg.[02.]log
(=3D=3D) intel(0): Silken mouse enabled
(II) intel(0): Initializing HW Cursor
(II) intel(0): No memory allocations
Xorg.1.log:
(EE) FBDEV(0): FBIOPUTCMAP: Invalid argument
Last message floods the log file I get =
grep '(EE) FBDEV' /var/log/Xorg.1.log | wc -l
144356
