<pre>Originally reported to openSUSE bugzilla:
<a href="https://bugzilla.opensuse.org/show_bug.cgi?id=1031462">https://bugzilla.opensuse.org/show_bug.cgi?id=1031462</a>
The i915 in 4.11-rc kernel seems to have a regression regarding VT switch.
When the machine is booted with an external monitor (HDMI or DP), the mode is
set on both eDP and HDMI/DP, then switching to VT1 from X leads to the frozen
screen.
It's not really a crash but likely the atomic modeset failure like bsc#1018358,
as you can go back to X via alt-F7 again.
The 4.10 kernel works fine, so it's a regression. The problem is reproduced on
Dell E7270 laptop with Skylake chip.</pre>
