Even I  set drm_kms_helper_poll to N, and disable gpe11, the problem can not be resolved. 
Also I have installed the phc-intel(phc-intel_0.3.2.12.2~ppa1~loms~precise_all.deb).

cat /etc/modprobe.d/local.conf 
options drm_kms_helper_poll=N

Title:
  i915_hotplug_work_func cause system crash

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  i915_hotplug_work_func cause system crash

  NoteBook:X200
  lsb_release -a
  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 13.04
  Release:	13.04
  Codename:	raring
   uname -a
  Linux julien-X200 3.8.0-30-generic #44-Ubuntu SMP Thu Aug 22 20:54:42 UTC 2013 i686 i686 i686 GNU/Linux

  Mostly the notebook crashes when it restore to work from "suspend" status. Occacionally it also stop work when I use firefox for some time.
  When the problem happens, I can not use keyboard, mouse and I can not switch to terminal mode through ctl+alt+F1~F6.
  I can ssh to the notebook from other pc, but I can not kill Xorg or reboot the notebook. The proc xorg in "uninterruptable sleep" staus.
  It seems i915_hotplug_work_func has dead lock.

  Information from dmesg:
