It seems they just added a workaround to detect this problem and disable acceleration : (EE) intel(0): Detected a hung GPU, disabling acceleration. (WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Input/output error [ 1577.544230] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 1577.544247] render error detected, EIR: 0x00000000 [ 1577.544272] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 61238 at 61237) When acceleration is disabled, the thing becomes slower and there are some display problems: horizontal black lines may appear, aptitude ncurses interface is completely scrambled in urxvt with transparent background, ... I have also tried 2.6.34-1~experimental.2 with no change. I have tried to disable KMS but X refuses to start. I will try to rebuild 2.6.34 kernel with patches from here and let you know if this improves things. http://glasen-hardt.de/?page_id=707 -- panic("Aarggh: attempting to free lock with active wait queue - shoot Andy"); 2.0.38 /usr/src/linux/fs/locks.c
