Hi,
I see a *lot* of these warning in 3.13.1.
3.12.x never showed this problem.
Any ideas?!

Can you please try latest the drm-intel-nightly git branch from
git://anongit.freedesktop.org/drm-intel ?
If that one's still affected then please boot with drm.debug=0xe added to
your kernel cmdline, reproduce the WARN and attach the complete dmesg.
Thanks, Daniel

Hm, this one doesn't contain the WARN backtrace when the driver loads.
Does it only happen occasionally? If so can you please try to grab a
dmesg with drm debugging enabled and the backtrace in it?

Hi,
the WARNINGs did only show in 3.13.1 without the debug option. With the
debug option turned on the WARNINGs show up in neither drm-intel-nightly
nor 3.13.2.
So either the debug option somehow interfere with the WARNINGs or the
bug was fixed between 3.13.1 and drm-intel-nightly resp. 3.13.2.

Can you please double-check that the bug is gone in 3.13.2, even without
the debug output enabled? I've looked at the stable patches and there's
nothing for i915 between .1 and .2.

Mhh. strange. I don't encounter these warning anymore with 3.13.2...
Maybe something else did trigger those?!
Anyway, I'll watch out for those warning in the future. And a big thanks
for your great support.
I'll update to 3.13.3 now.
