Few updates on this, the issue seems to be related to mesh shaders:
RADV_DEBUG=hang works because under the hood it also enables sync shaders so you can just do RADV_DEBUG=syncshaders
The mesa team have reported it to the fw already and they had put a workaround in the CI a year ago already
this RADV_DEBUG=nomeshshader may also work depending what version of mesa you are running.
Another issue to keep track will be Making sure you're not a bot!.
I’m following up regularly, if there is any fix from upstream projects and I know about it I’ll update this thread
