(In reply to Michel DÀnzer from comment #3)

The Xorg log file doesn't have any messages corresponding to those in dmesg.
Was it really captured after reproducing the problem?
Does
https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/merge_requests/
15 help or the freezes by any chance?

I checked again, but it doesn't print anything on Xorg log.
Those "device removed" are always shown after the freeze, not sure if related.

I tried that patch but it doesn't seem to make any difference.

I'm not sure about the freeze you experienced. I'm having similar issues on
latest Manjaro (4.18-4.19) that after wakeup, there are intermittent screen
freezes for a few seconds every 2-3 minutes. Aside from the good old
VBLANK-related error messages (like those in the attached dmesg), no more
errors are being recorded in the log except the system keeps freezing like that
unless I reboot.

The patches in my old bug report (which were eventually merged at some time
around 4.17) did not fix the root cause but at least fixed the 100%
reproducible kernel panic I used to have.

The problem has been observed on the same laptop I use for work (which was also
the one I used to test and report the previous bug), and for that reason, I'm
still not confident about locking the screen (since LightDM GTK Greeter doesn't
honor the "Timeout until the screen blanks", nor related settings in power
options), as the risk of losing unsaved work is still there.
