 Hi All,
 
 I can reproduce it and interested in moving this forward so I added the 
 diagnostic option to a custom kernel config (amd64, 10.1), built the 
 kernel and let it crash. This is what I got from gdb backtrace:
 
 #0  0xffffffff80239985 in cpu_reboot ()
 #1  0xffffffff80c5e75b in kern_reboot ()
 #2  0xffffffff80c94b8f in vpanic ()
 #3  0xffffffff80c94c64 in panic ()
 #4  0xffffffff80db3f82 in linux_ww_mutex_unlock ()
 #5  0xffffffff80db604f in ttm_bo_release ()
 #6  0xffffffff80905aa0 in amdgpu_bo_unref ()
 #7  0xffffffff80962aa1 in amdgpu_vm_free_table ()
 #8  0xffffffff8096351d in amdgpu_vm_free_pts ()

 #11 0xffffffff80b09a90 in drm_file_free ()
 #12 0xffffffff80ad98fd in drm_close ()
 #13 0xffffffff80c39ce8 in closef ()
 #14 0xffffffff80c39ea0 in fd_close ()
 #15 0xffffffff80c9ea42 in sys_close ()

 #18 0x0000000000000015 in ?? ()
 #19 0x0000000000000000 in ?? ()
 
 Let me know if I can add anything else.
 
 Best regards,
