Hi, since kernel 3.18 I'm no longer able to run X on my machine. While 3.17.6 is fine, 3.18 leaves me with a black screen when starting X. Booting into runlevel 1/3 is fine. I did a "git bisect", and the offending commit is this one: [root@kiera linux-git]# git bisect bad 83f45fc360c8e16a330474860ebda872d1384c8c is the first bad commit commit 83f45fc360c8e16a330474860ebda872d1384c8c Author: Daniel Vetter <daniel.vetter@xxxxxxxx> Date: Wed Aug 6 09:10:18 2014 +0200 drm: Don't grab an fb reference for the idr [....] I double-checked, and 3.18 is fine with this commit reverted. My machine is an Asus U45JC laptop, and the CPU is an Intel i450M (Ironlake). Please contact me if I can help in any way (I'm subscribed to lkml, but not to other X or kernel related lists). Thanks, Heinz. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
