dmesg

I'm using 5.4.x kernels for quite some time. And recently X server started to
hang sometimes after switching users. It starts using 100% CPU and killing it
with sigkill is the only thing I can do. I'm using GNOME, so each user has its
own X server.

I believe this is caused by the following patch that was included in 5.4.56:

"drm/amd/display: Clear dm_state for fast updates"

But since the issue is not 100% reproducible, I need some time to confirm it.


From dmesg:
