(In reply to Witold Baryluk from comment #0) > > It started few weeks ago, and I am getting sporadic screen lookups. Did the kernel get upgraded to a newer version around that time? > $ dmesg > [37571.611965] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update > failure on pipe A (start=163606 end=163607) time 560 us, min 1192, max 1199, > scanline start 1172, end 1213 Are there any other error messages in dmesg after this? Maybe attach the whole dmesg output. It looks like maybe a DRM (driver) error path doesn't unlock dev->mode_config.mutex, so any code trying to lock that hangs.
