Lenovo Intel i915 Video Drivers in Linux, Part 3

Problem Scenario/Steps:
Lenovo T460s
thinkpad ultra dock P/N SD20A06046 Type 40A2 S/N M3-A0AC8E 16/11+ fedora 26/27/28/29, according to my records any kernel since 4.15.9-300.fc27.x86_64

  1. Dock laptop in docking station with two connected monitors, one HDMI and one DVI.

  2. Undock laptop.

  3. Redock laptop → screen failure and system lock until undock again. Leave it long enough and it will reboot itself.

This issue was resolved by work in the 4.20 kernel!
