yes that is what i was referring to.  I do not have an AMDGPU system 
myself but have been told several times that it is required.

interesting, it looks like the kernel module and firmware modules do 
load.  one thing you may want to test is setting the 
"debug.debugger_on_panic=0" sysctl knob before loading the amdgpu.ko.  
hopefully this will allow you to get into a debugger before the system 
locks up.
