dmesg

Hardware: Lenovo ThinkPad T460P + Ultra Dock
CPU: i7-6820HQ
Additional GPU: gtx 940m.
Kernel: 4.13.10

Problem: Hotplugging an external monitor in the dock's DisplayPort doesn't work. Having the monitor plugged in at boot might work if the stars align.

Please see 118.920287 in dmesg for the hotplug event.

First of all. Sorry about spam.
This is mass update for our bugs. 

Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
If bug investigation still in progress, please ignore this and I apologize!

If you think this is not anymore valid, please comment to the bug that can be closed.
If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.

Could you provide a dmesg log booting with drm.debug=0xe?
Comment 3 Jani Saarinen 2018-04-25 09:26:49 UTC 
Please test latest drm-tip: https://cgit.freedesktop.org/drm-tip?

Hi Jani.

I'm no longer in possession of the thinkpad, so I will not be able to provide further information. Feel free to close the bug, sorry!
