Thanks for the trace!

Replaying the trace a few times is enough to reliably to reproduce the hang.

Using AMD_DEBUG=nongg seems to prevent it so it could be a temporary workaround
until a proper fix is found.
Could you confirm this on your system?

This trace file is very small (only one frame) and doesn't hang here.
