Title:
[HP ENVY 15t-3200 CTO Notebook PC] Intel DisplayPort Buffer Underrun
Status in “xorg” package in Ubuntu:
New
Bug description:
Similar to Bugs #1239186, #1290400
AMD hybrid video. Fglrx drivers are not installed, so it's
effectively an Intel HD4000 Display adapter.
Displayport monitor randomly blacks out, usually during load (playing
videos, audio, or both).
Turning on debugging in the drm module, I see:
[ 227.074336] [drm:ivb_err_int_handler], Pipe A FIFO underrun
[ 227.074350] [drm:cpt_serr_int_handler], PCH transcoder A FIFO underrun
