journalctl output for last boot to crash
I'm experiencing a random, but consistent hard-free (cannot switch virtual terminals) running an nVidia card with three monitors under Fedora 25. Recent kernel and driver updates have seemed to make this freeze much more frequent (5-6 times in two work days).
Journalctl -b -1 output is attached. Most relevant lines are:
kernel: nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
kernel: nouveau 0000:01:00.0: fifo: gr engine fault on channel 12, recovering...
kernel: [drm:drm_atomic_helper_swap_state [drm_kms_helper]] ERROR [CRTC:37:head-0] hw_done timed out
kernel: [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:37:head-0] hw_done timed out
kernel: [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:37:head-0] flip_done timed out
A possibly related bug is #96562, but it is old and hasn't received any attention, so I'm opening a new one.
