Bug description:
Hi,
I'm using a new Skylake Thinkpad T460s with and external monitor
connected via Displayport and Ubuntu 16.04 and the latest kernel as of
today: Linux test 4.4.0-17-generic #33-Ubuntu SMP Tue Mar 29 17:17:28
UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
X will from time to time lock up when the computer is left idle for a long time and both displays (laptop and external) go to sleep and then woken up.

Attached is the full kernel log from boot until the issue happens, at which point, if I have a lockup of X I need to reboot to get back to normal.
I don't know if this particular bug I'm reporting is the one
responsible for the lockups, as I've isolated 4 different
warning/error messages which separately or in combination may be the
cause. I'm reporting all of them now in separate bug reports.
Please let me know if any information is missing.
