[Bug 1550779] Re: [i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches
Hubert Hesse, the next step is to fully commit bisect from kernel
4.2.0-27 to 4.2.0-30 in order to identify the last good kernel commit,
followed immediately by the first bad one. This will allow for a more
expedited analysis of the root cause of your issue. Could you please do
this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.
Thank you for your understanding.

** Tags added: needs-bisect

Title:
[i915]] *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
