on bug 104001
from Dennis Schridde
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): [Fri Mar 2 21:05:33 2018] amdgpu: [powerplay] pp_dpm_get_temperature was not implemented.

Most applications that hang can be killed with SIGKILL, except the X server and a few others, which will be zombies forever.
