--- Comment #9 from Grazvydas Ignotas <notasas at gmail.com> ---
Is the process still alive when you ssh to the system with a hung GPU? If it
is, you could attach gdb and try to get a backtrace of a hung thread.

You can try at least a few other things:
* compile mesa with --enable-debug if you aren't already, it will enable
asserts that might detect something bad
* set a RADV_TRACE_FILE=/path/to/file environment variable, it will then try to
write out trace of GPU commands to that file if/when it detects a hang.

The trace file sometimes takes a few tries to produce successfully, but if you
can get it, it might help to find the cause of the hang.
