options KUBSAN on UEFI machine

[Masanobu SAITOH <msaitoh%execsw.org@localhost>]

 Hi.

 I have two UEFI based machines. I noticed both of them didn't boot
with KUBSAN. After loading kernel, the video console is cleared,
the cursol went upper left and then hang. I couldn't see the
NetBSD's copyright message.

 Is this known problem?
