<pre>I have the same issue:
Apr 28 12:21:28 morfikownia kernel: [drm:ironlake_irq_handler [i915]] *ERROR*
CPU pipe A FIFO underrun
Apr 28 12:21:28 morfikownia kernel: [drm:ironlake_irq_handler [i915]] *ERROR*
PCH transcoder A FIFO underrun
$ uname -a
Linux morfikownia 4.5.0-1-amd64 #1 SMP Debian 4.5.1-1 (2016-04-14) x86_64
GNU/Linu
So it looks like in 4.5 this isn't fixed. For now I'm not able to test
v4.6-rc5.</pre>
