Title:

SCHED_ERROR 20"
Status in xserver-xorg-video-nouveau package in Ubuntu:
Confirmed
Bug description:
After waking from suspend kern and syslog are filled following:
Aug 2 12:35:20 mycomp kernel: [ 4224.589205] nouveau 0000:01:00.0: fifo:
SCHED_ERROR 20 []
Aug 2 12:35:20 mycomp kernel: [ 4224.589216] nouveau 0000:01:00.0: fifo:

Aug 2 12:35:20 mycomp kernel: [ 4224.589228] nouveau 0000:01:00.0: fifo:
SCHED_ERROR 20 []
Fills up root rapidly within minutes and therefore freezes the system
and systemd-journald runs with CPU 100%. If root is filled completely,
the computer is unbootable and can only be recovered through rescue
mode.
