I've got Ubuntu 16.04 with up to date oibaf drivers on Ivy Bridge laptop
(i7-3520M). From time to time I get this in logs:

[53430.461898] drm/i915: Resetting chip after gpu hang

They usually come in groups of several and they most often (but not only) seem
to happen after resume or when disabling screensaver.

I'll attach card error output. Please let me know if I can provide more
information.

Thanks!
