sporadic system freeze after log in

[Marco]

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:
