<pre>Ok, i've gone ahead and bumped my kernel to this version:
Linux rnavarro-thinkpad 3.13.0-994-generic #201401140526 SMP Tue Jan 14
10:27:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
I went ahead and added a dump of the intel_reg_read output to rc.local to get
an early dump.
I then manually ran a dump right when I logged in, and again a few more times
after it happened again.
Here is the kernel log:
<a href="https://bugs.freedesktop.org/attachment.cgi?id=92058">https://bugs.freedesktop.org/attachment.cgi?id=92058</a>
P.S. This was a particularly good one, my main monitor didn't even turn back on
this time after the underrun.</pre>
