Subject: i915 warning on skylake with current master (12f03ee)
Hi,
(This is the first time I report an issue here so I'm sorry if I'm
doing something totally wrong (likely)).
I have a new skylake system with i7-6700k. I have some issues running
ArchLinux and the 4.2 kernel with the intel graphic driver (hang on
ioctl call etc) and have seen the computer spontaneously shuts off
(which may or may not be related to the graphic issue). I know there's
a lot of fixes in the master so I decided to see if I can have any
luck.
I'm not sure if the git version resolved my issue but I did notice
that I see a warning printed at boot time that I didn't see before
(see the dmesg output below). The display manager (sddm) also refuse
to start at first complaining X "stopped" but could start if I restart
it from the terminal.
I also attached the output of `lspci -v` in case it is useful.
