dmesg with drm.debug

Can't say anything about regression. I've purchased dock just a few weeks ago.

Attached dmesg contains full log from boot. Now I've got different call stack
but using same steps to repro:

1. boot laptop undocked and suspend
2. dock it and wake up using power btn on dock.
3. suspend it docked and undock.
4. undock and wake up, and then suspend again
5. repeat step 2.

So basic idea is to connect/disconnect dock while machine is suspended.
