[Piotr Wieczorek <1534260@xxxxxxxxxxxxxxxxxx>]

Because of problems with graphics on v4.5-rc1 (maybe because I'm using
intel-linux-graphics-installer, or maybe it's the i915 drivers issues)
I've tried earlier kernels.

On v4.4 the bug seem to be fixed (complains about i915 firmware)
On v4.3.4 the bug is still there (does not complain about the firmware)

On both of them there were some display issues (flickering screen), so I
had to go back to the standard 15.10 kernel.
