--- Comment #3 from Mikhail Morfikov <morfikov at gmail.com> ---
I think I know what causes this problem -- I had the following kernel
parameters set in extlinux:

i915.enable_rc6=7 i915.lvds_downclock=1 i915.semaphores=1 i915.fastboot=1

I removed them from the kernel line because the problem started to occur 5-10
times a day.

I don't know if one of the parameters is to blame or all. I just used them for
power save mode, at least that's what they said on the internet.

Anyway, now I don't get the error.
