Charles Lease, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
Hw no longer available for testing, so closing.

Hopefully https://patchwork.kernel.org/patch/2841344/ is the right fix.
Can you please test the above patch?
Unfortunately, as I said in comment #17, I don't have access to the IVB
hardware anymore so I can't test the patch.

If someone can reproduce this, can they read back register 0x20f4?

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?

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.

Can you please check whether cherry-picking the referenced patch to a stable
kernel fixes the issues, too?
Yes, applying it on top of the Ubuntu 3.8 kernel worked fine.

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.
