options EFIRT: immediate crash of CURRENT

[Hartmann, O.]

Playing around with some EFI related options and putting 

options EFIRT

into the kernel config, results in an immediate crash after booting,
see screenshot attached.

This happens on non-EFI booting systems as well as EFI capable systems.
The screenshot is taken from a box with UEFI firmware, but disabled and
used via CSM/BIOS, but with option enabled.
