--- Comment #14 from oliver.pahl at googlemail.com ---
I experience the same issue on kernel 4.2-rc6. Before that I needed to boot
with the i915.preliminary_hw_support=1 i915.enable_ips=0 kerne parameters,
otherwise switching VTs was broken. Now switching works but I get the vblank
issue and graphical artifacts. If you need more info or think this is a
different bug, please state it so I can open another one. Also contact me if
you need more info.
