gnome-session-3.18.0-1.fc23.x86_64

How reproducible:
every-time

1. boot into F23
2. put laptop into dock station

Actual results:
laptop freezes with black screen or (sometimes) last screen

Comment 2 Honza Horak 2015-09-29 07:00:47 UTC 
I've tried it with kernel-4.3.0-0.rc2.git1.1.fc24.x86_64 and at least putting into docking station works fine. (I'll let know whether other problematic actions are problem, but expecting they aren't)
Comment 3 Justin M. Forbes 2015-09-30 14:49:47 UTC 
I believe this has been fixed with kernel 4.2.2-300. Would you mind testing and letting me know?
Comment 4 Honza Horak 2015-10-07 10:18:08 UTC 
Yes, it works now. Thanks.
