            Bug ID: 206225
           Summary: nouveau: Screen distortion and lockup on resume
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.4.12
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: derchiller-foren at online.de
        Regression: No

When starting suspend or hibernate, it takes approx. 2 mins until the system
actually begins to write RAM contents to disk (when hibernating), although the
screen is switched off immediately.

When resuming, video is completely distorted. Sometimes I am able to restart
Gnome via Alt+F2 or to switch to a VT, but sometimes the system doesn't react
at all.

Syslog contains nouveau errors:

On last resume from hibernate, it additionally contained a call trace
associated with nouveau:

I already encountered that issue on 5.3.9 and it vanished after installing
Debian package 'firmware-misc-nonfree', but now with 5.4.12, it is back again,
while 5.4.11 was ok.

I should mention that even with 5.4.12, this only happens after having worked
with the system for a while, not when suspending/hibernating immediately after
startup.
