Title:
[Lenovo ThinkPad X220] *ERROR* CPU pipe A FIFO underrun - Xorg
glitches

Status in linux package in Ubuntu:
Incomplete

Bug description:
Upgraded linux-image-extra-4.2.0-30-generic I see graphic glitches,
looks like the graphic buffer gets screwed up

- funny repetition's patterns (back in time glitches)
- black screen (<1sec)
- graphic errors

I can influence the severity of the issue with switching windows and
using certain programs, e.g. Google Maps in chrome causes this issue
reproducibly
