           Summary: nouveau: BUG: kernel NULL pointer dereference in
                    nouveau_bo_sync_for_device
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.11.0
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx
          Reporter: dave.mueller@xxxxxx
        Regression: No

Since kernel 5.11, the nouveau driver crash with a NULL pointer exception.
Below is the (stripped) dmesg output from kernel 5.12, which still shows the
same problem.
The same (old) hardware works fine with kernel 5.10.
