Yeah this is definitely a mesa problem. Any idea when this will be
pushed to saucy's repo? I have computers waiting to be upgraded to 13.10

The bug has been confirmed by Mesa upstream for all versions prior to
9.2.3.

This should be confirmed (it is not affected by the kernel version), and
marked as affecting Saucy and Trusty because they both use the Mesa 9.2
series so both Saucy and Trusty get updated to Mesa 9.2.3 as noted
upstream.

Fixed in Mesa 9.2.3 (out today), the upcoming Mesa 10.0 release, or Mesa

This fixes the Sandybridge-specific GPU hang where i915_error_state (aka

Sorry to re-open but I wanted to include one more detail - either a
recent update fixed this for me, or a recent change I made to my BIOS
settings (changing my fan speed from normal to turbo in my
motherboard BIOS) has made me unable to reproduce this hang, even after
long periods of scrolling
I can tentatively confirm that this is working for me as well.
Will run some more tests later.

I'm trying to test this out now. Keep in mind this may not be a kernel
issue and could be something else wrong with the stack.
Here are some interesting stuff from dmesg:

How do I tag?
But I cannot test upstream kernel as it would just freeze my DE upon
boot. Not sure what's going on.
