[4.0.0-rc3-24042-g5fb0f7fa] BUG: NULL pointer dereference in DRM

From: Thomas Meyer
Date: Sun Mar 22 2015 - 12:46:31 EST


Hi,

two things:

1.) the i915 drivers seemed to have crashed, and/or Xorg somehow got
stuck. But I could ssh into the machine and extract below the kernel
log.
See the below "BUG: unable to handle kernel NULL pointer dereference at
(null)" and "BUG: scheduling while atomic: Xorg.bin/1398/0x00000003"

2.) I tried to power off the machine via the halt command. but the
process somehow got stuck and I needed to force a power off by pressing
the power off button for 5 seconds.
("device-mapper: ioctl: unable to remove open device luksRoot"?)

any ideas what went wrong here?
