Comment 2 Oliver Neukum 2015-10-14 07:52:41 UTC 
This is likely the same issue as reported in
https://bugzilla.kernel.org/show_bug.cgi?id=104041
Comment 3 Oliver Neukum 2015-10-14 08:14:19 UTC 
The warning is also triggered by booting in the undocked state.

Yes, I thought we had that covered already, but apparently now. Let's track this here anyway, we're migrating all bugs to fdo bugzilla.

Please attach dmesg with drm.debug=14 module parameter set, all the way from boot.

I'm having the same has_drrs error on a completely different laptop:

didn't see this one when filed 
https://bugs.freedesktop.org/show_bug.cgi?id=92997
In my case it is also HP laptop but with Intel and Radeon. And I also get entire system stalled quite frequently whenever manipulation with displays is happening

*** Bug 92997 has been marked as a duplicate of this bug. ***
Comment 9 Max Lin 2015-11-24 10:17:22 UTC 
I've the likely same issue on my HP 820 G1 laptop with very similar call trace.

Still present for me in 4.3.1 on Dell XPS 13 (i7-3537U)
Comment 11 Andreas Gnau 2015-12-23 00:25:21 UTC 
Fixed for me in 4.4-rc5. Can someone else confirm this?

The change was merged in 4.4-rc4:

I'm using an HP EliteBook 840 G1 attached to an "HP 2013 UltraSlim Docking Station" with two external displays and applying the patch to Linux 4.3.3 has fixed the error for me. Thanks!
