Re: i915 driver gpu hung kernel 3.11

[Bruno PrÃmont]

Hi Stephen,

You may want to CC intel-gfx@xxxxxxxxxxxxxxxxxxxxx  for i915 issues (even
if you are not subscribed and you mail will wait for a moderator to let
it go through).

In case of intel GPU hangs you should at least include
/sys/kernel/debug/dri/0/i915_error_state, probably submitting as a
bug report on bugs.freedesktop.org due to its size.

If you have any indication on what triggers the hang, please add!

Bruno
