I too am having the same issue. I'm running on kernel 3.12.6 (just updated)The issue happens less frequently, but it still happens and it's quite annoying.Previously I would just get lines like this:[ 342.071567] [drm:ilk_display_irq_handler], Pipe B FIFO underrun[ 342.071584] [drm:cpt_serr_int_handler], PCH transcoder B FIFO underrunBut after the recent kernel update it looks like there are some more debug messages being sent out like this:[ 624.430107] [drm:i915_driver_open],[ 624.439972] [drm:i915_gem_context_create_ioctl], HW context 1 created[ 624.450177] [drm:i915_gem_context_destroy_ioctl], HW context 1 destroyedI have a bug open for this, but I haven't heard a response on next steps unfortunately :(--

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): https://bugs.freedesktop.org/attachment.cgi?id=91827
