dmesg i915_error_state Xorg.0.log


after https://bugs.freedesktop.org/show_bug.cgi?id=52382 resolves many problems with distortions, know the X server crashes everytime I start glxgears.

dmesg | grep Kernel
[    0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=ee43639f-2293-494b-a118-fce9f467b11b ro quiet enable_mtrr_cleanup mtrr_spare_reg_nr=1 i915.i915_enable_rc6=1 i915.semaphores=1

I tried it without the arguments i915.i915_enable_rc6=1 i915.semaphores=1 and it do not work.

# cat /etc/X11/xorg.conf.d/20-intel.conf 
Section "Device"
   Identifier	"HD 2500"
   Driver	"intel"
   Option	"AccelMethod"	"sna"
   #Option	"AccelMethod"	"uxa"
   Option	"DRI"		"true"

There is no difference between uxa and sna.

Please tell me if i forget anything which can help.
