Comment 1 Daniel Vetter 2013-04-17 16:24:15 UTC

Your gpu most likely died. If everything works according to plane you should have a gpu hang dump in debugfs in i915_error_state. Please re-hang your machine and attach the contents of that file.

ope - I do have already a back ground job running which saves that data into /var/tmp - but I did not have any data there.

Comment 4 Rodrigo Vivi 2014-01-30 09:27:49 UTC

Do you still see this issue with latest drm-intel-nightly from http://cgit.freedesktop.org/~danvet/drm-intel/log/?h=drm-intel-nightly

Could you please provide new dmesg with kernel booted with drm.debug=0xe along with new i915 error state?

oh no - it is fine now with 3.12.x
