Description:
Since linux 3.16 (and persisting with the new 3.16.1), I'm getting this errors at boot. It doesn't seem to affect anything (yet):

ago 15 10:02:49 UGI kernel: [drm:ilk_display_irq_handler] *ERROR* Pipe A FIFO underrun
ago 15 10:02:49 UGI kernel: [drm:cpt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder A
ago 15 10:02:49 UGI kernel: [drm:cpt_serr_int_handler] *ERROR* PCH transcoder A FIFO underrun

Anyone might know what's going on? If necessary, I'll post this to LKLM.
This task depends upon
