While watching tv with vdr-sxfe and xv video driver, I've got following
entries in syslog:

Apr 27 20:51:47 Supernova kernel: [  912.313745] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 448397, at 448397], missed IRQ?
Apr 27 20:52:10 Supernova kernel: [  934.542892] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 457347, at 457347], missed IRQ?
Apr 27 20:54:55 Supernova kernel: [ 1099.236105] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 554961, at 554961], missed IRQ?

Shouldn't be it for example "waiting on 448398, at 448397"? Or what are
those numbers? Just an idea... Multithreading problem with 4 cores?
Uncle Jim Beam out... ;)
