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. --=20 You are receiving this mail because: You are the assignee for the bug.=
