Bug Description

I upgraded to saucy yesterday, rebooted, and within 30 minutes of use, X hung on me.
It seemed like it might be a regression of bug 1097315 which occurred during raring, so I booted into a raring kernel. This bug report is occuring with the raring kernel (3.8.0-21-generic).

more-info.tar.gz: i915_error_state and additional dmesg Edit (485.5 KiB, application/x-tar)

These files were after dmesg instructed there might be more info in 'i915_error_state' with message like:
[176339.808126] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[176339.808141] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state

So, I copied both of the following here.
sudo cp /sys/kernel/debug/dri/0/i915_error_state 0.i915_error_state
sudo cp /sys/kernel/debug/dri/64/i915_error_state 64.i915_error_state

Then also collected dmesg as it had more info now than it did when 'ubuntu-bug'
collected it.

just hung again on 3.9.0-2-generic (maybe 2 minutes of uptime).
This time, the mouse cursor moves, but focus doesn't change, and no typing input.
screen will dim, then mouse movement brings it back to full brightness.

nothing in dmesg well after 120 seconds waiting.

The fixes for the kernel deadlock should be in 3.10; the root cause of the primary bug is in mesa.

Chris, thanks.
Just for reference, I just reproduced with these xserver/kernel:

$ dpkg-query --show linux-image-3.9.0-6-generic xserver-xorg-video-intel
linux-image-3.9.0-6-generic 3.9.0-6.13
xserver-xorg-video-intel 2:2.21.9-0ubuntu2

booting the old kernel (3.8.0-21-generic) doesn't seem to show the problem.

The following appears to have fixed the issue. I've been running it for ~ 6 hours now.
