gzipd i915_error_state
I get intermittent hangs of the intel GPU on my laptop, usually every 5-15mins
while gaming, during which Xorg tops out the CPU and the whole window manager
is very slow. This lasts up to a minute before generally returning to normal.
Even low-intensity games like Faster Than Light etc will trigger it, although
it seems to take less time to trigger with more demanding use (e.g. FTL took
nearly 2 hours to trigger it).
Hardware: Dell L702x laptop with i915 chip. Lspci -v reports:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA
controller])
Subsystem: Dell Device 0571
OS is Archlinux 64bit, running mesa 10.2.3-2 and xf86-video-intel-git
2.99.912.229.ge0523ad-1, although similar behaviour was seen on
xf86-video-intel 2.99.912-2.
Attached is the i915_error_state (gzip'd), the dmesg output, i915 kernel
options, and the Xorg log. I'm currently using Option "AccelMethod" "uxa" in my
Xorg config, although I have also tried "sna" which no difference in results.
Happy to test other xorg config / kernel options / driver patches. Just let me
know.</pre>
