Xorg.log


when I try to use xf86-video-intel-2.16.0  driver I got a black screen.
The details are reported in the attached file.
Comment 1 Chris Wilson 2011-09-17 02:52:29 UTC 
That's not the error-state, can you please attach /sys/kernel/debug/dri/0/i915_error_state following the crash. You may need to first "sudo mount -tdebugfs debug /sys/kernel/debug/" in order to make the error-state accessible.

I am sending i915_error_state file for you.
Thanks for solving this problem.

Bad news, it is just the expected 845g borkage.
