[Bug 1550779] Re: [i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches
Hi all, I was bugged by this both in Ubuntu 16.04 (any 4.4 kernel after release) and in ArchLinUX with all actual 4.5 kernels.
My solution was to take the 4.6 kernel on ArchLinUX (testing repository), after which I was cured from all difficulties. If you use VirtualBox with a new 4.4/4.5 kernel in your client, you get very often bugged by this failure.
--> If you can, use LinUX kernel 4.6.

Title:
[i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches
Status in linux package in Ubuntu:
Confirmed
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
