Patch: http://cgit.freedesktop.org/~danvet/drm-intel/commit/?h=drm-intel-fixes&id=55a254ac63a3ac1867d1501030e7fba69c7d4aeb Please test whether this fixes your issue. You can also try adding i915.i915_enable_ppgtt=0 to your kernel cmdline.

My guess is on the firmware load vs. suspend/resume fix that landed in -rc2. That one fixed resume on all the machines here, and -rc1 broke it on a lot of them. -Daniel -- Daniel Vetter daniel.vetter@ffwll.ch - +41 (0) 79 364 57 48 - http://blog.ffwll.ch ^ permalink raw reply [flat|nested] 6+ messages in thread
