Package: libdrm-intel1
Version: 2.4.56-1

Dear maintainer,
Using Linux 3.16-1-686-pae (version 3.16.2-3), I am having problems :
  - Hangs on boot most of the time (needs "hard" shutdown)
  - On resume (after a suspend to ram), screen backlight not powering on (needs a reboot, soft or hard)

I looked in /var/log/kern.log and found this, which might be linked :

Sep 14 10:08:11 yvan-macbook kernel: [    2.076128] [drm] GPU HANG:
ecode -1:0x00000000, reason: Command parser error, iir 0x00008000,
action: continue
Sep 14 10:08:11 yvan-macbook kernel: [    2.076130] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
Sep 14 10:08:11 yvan-macbook kernel: [    2.076131] [drm] Please file a
_new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
Sep 14 10:08:11 yvan-macbook kernel: [    2.076132] [drm] drm/i915
developers can then reassign to the right component if it's not a kernel
issue.
Sep 14 10:08:11 yvan-macbook kernel: [    2.076133] [drm] The gpu crash
dump is required to analyze gpu hangs, so please always attach it.
Sep 14 10:08:11 yvan-macbook kernel: [    2.076134] [drm] GPU crash dump
saved to /sys/class/drm/card0/error

Do not hesitate to ask more information if you need.
Thanks for your time and work,

According to that bug this is no longer an issue with current kernels,
so closing.  Thanks.
