Comment # 1
on bug 98874
from Michel Dänzer
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.
