<pre>I recently installed a new Radeon R9 380 and use the amdgpu driver. After some
random time my dekstop suddenly freezes, no input (mouse, keyboard, acpi
events) is possible. I still can login via ssh from another box and run some
commands but I do not see any error messages. Dmesg, .xsession-erros,
Xorg.0.log, journalctl are all clean.
I can erform either one of the following steps:
(A) Try to shutdown via the ssh session. I am kicked of from the ssh session
(obviously) but the box is is not powered off. Somewhere during the shutdown
process the box gets stuck. All the time I still see the frozen desktop. The
only option is to forcefully power off the PC by pressing the power button for
3sec.
(B) Do not try to shutdown completely, but initiate a "systemctl rescue". All
X11-related stuff is terminated (according to ps -elf), but I still see the
frozen desktop. "lsmod" still reports that amdgpu is used by approx. 35
processes. "rmmod amdgpu" kills the machine entirely, after that even my SSH
session is stuck, i.e. the shell never returned to its prompt. Any attempt to
login via SSH a second time fails. The only option is to forcefully power off.
After reboot: No error messages anywhere</pre>
