I've been bitten by this twice on a KDE desktop in the last 24 hours .. 
same error on both occasions :-(

error: [drm:pid1197:i915_gem_object_pin] *ERROR* WARN ON: obj->pin_count 
== DRM_I915_GEM_OBJECT_MAX_PIN_COUNT
pid 1197 (Xorg), uid 0: exited on signal 6 (core dumped)

  [ .. ]

error: [drm:pid16212:i915_gem_object_pin] *ERROR* WARN ON: 
obj->pin_count == DRM_I915_GEM_OBJECT_MAX_PIN_COUNT
pid 16212 (Xorg), uid 0: exited on signal 6 (core dumped)

I see only one change in the dev/drm2 sources (r309712) but there have 
been many in the vm code.

Any hints/pointers appreciated,

	Michael
