[Test Case]

See above. Not easily reproducible at will.

[Fix]

Pull in latest drm/vc4 fixes from github.com/raspberrypi/linux

[Where Problems Could Occur]

Modifications are limited to the drm subsystem so only the desktop image should be affected. Potential problems might show up as display (rendering) issues, crashes, freezes and/or kernel crashes/freezes.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[volker (vbueschken)]

Same issue for me
Ubuntu freezes after some time with same error messages in logfile

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-raspi/6.5.0-1010.13 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-mantic-linux-raspi' to 'verification-done-mantic-linux-raspi'. If the problem still exists, change the tag 'verification-needed-mantic-linux-raspi' to 'verification-failed-mantic-linux-raspi'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Juerg Haefliger (juergh)]

This is unverifiable at the moment, so wave it through.

[fprietog (fprietog)]

Even though the fix is unverifiable I can tell that after several days running the proposed kernel I haven't experienced the problem anymore.
