     What's broken in amdgpu?  There shouldn't be any ttm changes in amdgpu
     for drm-next.  Those all go through drm-misc.


It's not a TTM change.

The backmerge of drm-next into drm-misc-next broke amdgpu so that even
glxgears doesn't work anymore.

But each individual merge head still works fine as far as I can say.

Any idea how to track that down?
The backmerge brought in

   Fixes: 16e6eea29d7b ("Merge tag 'amd-drm-fixes-5.9-2020-08-07' ...)

which has quite a few commit. Maybe it's in one of them.

Nope, I have just double checked that I can revert either parent of the merge and the problem disappears.

I somehow need to figure out how to cleanly revert all patches in one branch one by one and then do a reverse bisect. Oh, sometimes I love my job :(

If anybody has a good idea how to do this please speak up.

Thanks,
Christian.


Best regards
Thomas
