Public bug reported:

I'm using a mostly-stock Quantal install on a Dell Latitude E6410. If I
stick with mostly xorg-edgers packages plus the Quantal shipped xserver-
xorg-video-intel, I'm fine. If I upgrade to any of the xorg-edgers Intel
driver releases from the last... Three months? At least? ...I get
anywhere from thirty minutes to a few hours of work done before the GPU
crashes repeatedly until it's declared "hung" and reset. Then Cinnamon's
toast, and so is the rest of my DE, and it's time to zap the X server
and restart the laptop.

I'd submit a bug with logs from an *actual* crash, but I've had to
disable apport entirely to stop it trying to process the GPU crash
information. *That* crashes the apport GPU sub-module.

Are there some known GPU crash / hang bugs re: the old Core i7-6x0
mobile CPUs? Something else going on? Do I need a newer kernel to *not*
get all these crashes? I see the last xorg-edgers 3.8 kernel currently
uploaded for Quantal failed to build for i386, and I'm not being offered
it through aptitude, so I'm very hesitant to pull down the 3.8 packages
and install them manually.
