Description Andy Furniss 2011-12-11 09:45:22 UTC

I don't use this box any more as such, and this is the first drm-core-next I've tried on it (Previous Kernel was d-r-t).

On loading kms I loose display, but the box is still alive.

startx hangs though, needing SysRq last line in xorg log drmOpenDevice: node name is /dev/dri/card0

From kernel log -

I tested some more and the latest working commit is

commit 822c4d9ae0d55a4fcea9f0a462bc6406a06692e2
Author: Jerome Glisse <jglisse@redhat.com>
Date:   Thu Nov 10 18:24:09 2011 -0500

 drm/ttm: page allocation use page array instead of list

Starting with the commit following that - 

commit 649bf3ca77343e3be1e0af8e21356fa569b1abd9
Author: Jerome Glisse <jglisse@redhat.com>
Date:   Tue Nov 1 20:46:13 2011 -0400

  drm/ttm: merge ttm_backend and ttm_tt V5

I get an Oops - but it is not the same as the one on head, I can start kms and fbcon is working.

When I startx I get-
