Ok.

This patch https://patchwork.freedesktop.org/series/64792/ might help: it won't
fix any issue, but when a timeout is detected it should allow the soft recovery
of the GPU.

Other things worth trying: setting AMD_DEBUG environment variables. I'd
suggest:

   AMD_DEBUG=zerovram,nodma,nodpbb

There are others (see mesa/src/gallium/drivers/radeonsi/si_pipe.c) to try if
these don't help.
