--- Comment #27 from Dennis Schridde <devurandom@gmx.net> ---
I run into this issue regularly with an AMD Ryzen 5 2400G (primary display,
connected via DP to the monitor) and an AMD Radeon RX 560 (not connected to a
monitor, secondary display according to mainboard firmware configuration).

After using my computer for some time, the graphics suddenly freezes and I see
lines like the following in dmesg (after logging in via SSH):

Everything apart from the graphics appears to continue to run fine, except any
application (e.g. started on the command line) that tries to talk to the X
server: They will hang.  Most applications that hang can be killed with
SIGKILL, except the X server and a few others, which will be zombies forever.
