 So I'm rolling with the patch at http://lanvaux.fr/.download/projs/support/NetBSD-amdgpu/diff
 The change since I last reported is that I silenced further outputs that were also either left off or rate-limited under Linux.
 
 It is not crashing with the patch however I am still getting these
 
   `warning: [drm] Fence fallback timer expired on ring gfx' (I put the dmesg output next to the diff.)
 
 Along with screen corruption: missing parts of glyphs inside of xterm (and I  believe widgets as well at times.)
 Sorry I forgot when I had synced and now I nuked those sources.  But it was fairly consistent.
 
 I am retrying with netbsd-10.
 I will also try taking a screenshot but I suppose that timeout warning *has* to go one way or another -_-
 
 Probably  my change is wrong somewhere too: I either commented out something that should be properly converted or return early 0 when something should actually be done (I think I check this one it checked-out, but I can look again.)
