Comment # 8 on bug 104362 from Andrey Grodzovsky

We can try and check the gfx command buffer for latest commands and CUs status
- 

Clone and build our open source register analyzer from here -
https://cgit.freedesktop.org/amd/umr/

After hang happens please get following outputs -

sudo umr -lb > umr_dump
sudo umr -O verbose,use_colour -R gfx[.] >> umr_dump
sudo umr -O halt_waves,use_colour -wa >> umr_dump
dmesg > dmesg_dump
