</blockquote></div><br><pre class="" id="comment_text_14" style="white-space:pre-wrap;width:50em;color:rgb(0,0,0)">I've gone ahead and updated to the latest nightly:
Linux rnavarro-thinkpad 3.13.0-994-generic #201401100405 SMP Fri Jan 10 09:05:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
The release done on 1/10/14
I'm still getting the underruns, they're actually a bit more frequent now. Right after I logged in I got one one my second monitor, and then shortly after another on my first.
The latest log can be found here (01-10-2014 drm-intel-nightly):
