Hello,

I am encountering a kernel panic with the error in the subject line using kernel 5.14.0 (final). Kernel 5.14.0-rc7 works without issue for me so looking back at the last amdgpu commits for 5.14.0 (final) not sure which one is at fault and causing the panic - https://cgit.freedesktop.org/drm/drm/tag/?h=drm-fixes-2021-08-27

I filed a kernel bug here - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942684 with a full log attached in the report. I am not sure if a separate bug report is needed in drm kernel? I'm hoping I can get some advice on who needs to be aware of this bug or how to bring it to the right developer's attention...

Below is the boot log and the specific error message:
