--- Comment #11 from Adam Pigg <adam at piggz.co.uk> ---
Also suffering flickering after a recent update to opensuse tumbleweed.

Hardware:
HP i5 laptop (limited edition star wars)
00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated
Graphics (rev 07)
Kernel:
Linux linux-f1uu 4.5.0-1-default #1 SMP PREEMPT Wed Mar 16 17:30:21 UTC 2016
(b2c9ae5) x86_64 x86_64 x86_64 GNU/Linux

Seems mainly happens on battery I think.  Flicker happens a few times a minute.
 In dmesg i get 
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun
but not every time the flicker occurs, and maybe isnt related but seems like it
might be.
