Does the crash happen often, or was it a one-time occurrence? If you can reproduce the crash, you might try creating an /etc/X11/xorg.conf file that turns off SNA (using UXA instead):

Section "Device"
 Identifier "Card0"
 Driver "intel"
 Option "AccelMethod" "uxa"
EndSection

Just a bug in the local xmir patch. Fixed upstream.

[Chris Wilson (ickle)]

Note that you end up there due to a bug in mir...

[Chris Wilson (ickle)]

The secondary bug we have a fix pending, but unless we fix the first bug we still won't be able to start X.
