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 at kernel-bugs.osdl.org

Since kernel 5.11, the nouveau driver crash with a NULL pointer exception.
