        <pre>This is on a Sony Vaio Pro 13 (Haswell) running Fedora 26.

After upgrading from kernel-4.11.11-300.fc26.x86_64 to 4.12.5-300.fc26.x86_64,
I no longer get any video output (in particular: the LUKS password prompt) on
the external monitor connected to the HDMI port. It's only displayed on the
internal LCD. The external monitor shows the expected video output only after
Xorg starts.</pre>
