  --> https://bugs.freedesktop.org/attachment.cgi?id=125629&action=edit
dmesg from 4.8-rc1 with drm.debug=0xe

I just tried the current 4.8-rc1 kernel and it results in blank displays and a
traceback in the system log. 4.7 and earlier versions work fine.

Hardware: Thinkpad L460 in UltraDock with 2 external screens (DVI+HDMI )
Software: Arch Linux with Kernel 4.8-rc1

Could be related to bug 97182.
