Bug description:
With kernel
Linux version 5.4.0-77-lowlatency (buildd@lgw01-amd64-028) (gcc
version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) #86-Ubuntu SMP PREEMPT
Thu Jun 17 03:26:36 UTC 2021 (Ubuntu 5.4.0-77.86-lowlatency 5.4.119)
in Ubuntustudio I got two system freezes (video frozen, mouse and
keyboard without function) some seconds after login in the last days.
In the journal I see in both cases a kernel error referring to
drm_kms:
