https://bugs.freedesktop.org/show_bug.cgi?id=29738 --- Comment #9 from Alexandre <alexandref75@xxxxxxxxx> 2010-08-26 00:33:25 PDT --- In my bisect (I tried to reduce the number of tests) by restricting the commits to the drivers/gpu/drm include/drm directories. The commit I got is the one below. I am not 100% confident since getting the good is difficult (the bad is easy) and some combinations keep getting a different bug that is described below. 7a6b2896f261894dde287d3faefa4b432cddca53 is the first bad commit commit 7a6b2896f261894dde287d3faefa4b432cddca53 Author: Daniel Vetter <daniel.vetter@xxxxxxxx> Date: Fri Jul 2 15:02:15 2010 +0100 drm_mm: extract check_free_mm_node There are already two copies of this logic. And the new scanning stuff will add some more. So extract it into a small helper function.

The drm restarts. I do not know if this error is masking the fatal error to occur. I do not see this error in 2.6.35 or 2.6.25.2.
