I hate to say again how little I know about kernel module loading, but by any
chance is there multithreading in the code that gets called when amdgpu.ko is
first loaded?  I can't help thinking that perhaps that code is returning
prematurely, before some initialization is completely finished and all locks
released.  If I knew where to put it, I would throw in a five-second delay at
the end of whatever gets called to load amdgpu.ko.
