--- Comment #1 from Michel Dänzer <michel at daenzer.net> ---
Sounds like a GPU hang, which is most likely caused by Mesa or LLVM. With the
environment variable GALLIUM_DDEBUG="pipelined 2000" set for the compositor or
Xorg process, the radeonsi driver might detect the hang and dump some
information about it in a file in ~/ddebug_dumps/ . Please attach that file
here.
The failure to recover cleanly from the problem is a kernel issue. You can try
setting amdgpu.lockup_timeout=2000 to make the amdgpu driver detect the hang
and try to reset the GPU, but it doesn't work reliably in general yet.
