Can you please check whether cherry-picking the referenced patch to a
stable kernel fixes the issues, too?

I've just sent out the stable backport request, so this should get fixed
in the next stable kernel releases (or one of the next, around the merge
window there's a bit a lag usually due to the high patch load).
Thanks for reporting this issue and please reopen if it breaks again.

On the same machine, I tried running SuperTuxKart on Arch Linux with
Linux kernel 3.10-rc2, mesa 9.1.2 and Intel drivers 2.21.6.
I seemed to get the same hang, even though 3.10-rc2 contains the above-
mentioned commit. I will attach the error state and relevant dmesg log.

Note that with IVB and MSAA I see lots of corruption with large swaths
of memory being overwritten with pixel values (lots of 0x
especially). That would include the possibility of overwritting context
memory. Isolating MSAA in mesa would be tricky... perhaps a hack to
disable?
