Ok, on a Sandybridge machine I also need the settings of all the i915
module options, i.e.

cd /sys/module/i915/parameters
grep .* *

You're running with rc6 enabled, can you check whether the bug goes away
when rc6 is disabled. You're also running with VT-d/dmar enabled, can you
disable that, too (leave rc6 enabled for that) either in the bios or with

intel_iommu=off

and check whether that might help.

Please attach the versions of libdrm, xf86-video-intel and mesa, too

Thanks, Daniel
