--- Comment #15 from Chris Paulson-Ellis <chris at edesix.com> ---
It still NULL derefd with that patch - in the same place, but with a different
call stack. However, after looking at where it was happening, I found another
commit to cherry-pick that fixes it:

afada5e0  drm/nv04/disp: disable vblank interrupts when disabling display

The first of the commits that was previously NULL derefing is now black screen
hanging instead, so I think I've found the problem commit - 2a44e499.

To recap...

The last working commit is d2edab4a with dea7e0ac & 095f979a cherry-picked.

The first hanging commit is 2a44e499 with dea7e0ac, 095f979a & afada5e0
cherry-picked.

I'm attaching the console output for these 2 runs.

Chris.
