I get this all the time. I have to disable dpms otherwise it takes a few
minutes before I can console cycle enough to convince the monitor to come back
on.

[ 1635.507939] [drm:ivybridge_set_fifo_underrun_reporting] *ERROR* uncleared
fifo underrun on pipe A
[ 1635.507947] [drm:ivb_err_int_handler] *ERROR* Pipe A FIFO underrun

Workaround is: xset -dpms at graphical login and remember to always login after
a boot!
