Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
It has helped me to add a NULL pointer check that was suggested at
http://lists.freedesktop.org/archives/dri-devel/2014-October/070663.html
I am not familiar with the code. But the change looks sane
and we need something fast at this stage of 3.18 development.
