I saw
   2977 root      20   0       0      0      0 R  99,3   0,0   5:18.68
   kworker/u16:39+amdgpu-reset-dev  

But the system is almost unusable, it takes seconds to print the
characters in terminal when connecting from a remote machine. Local,
the system doesn't care about keyboard anymore, except Sysrq.
Switching to another tty wasn't possible.

In some cases, even the sysrq keystroke won't be recognized and I need
to use the reset switch on the case.
