Hello Miod,

`disable ucc` has no effect (it doesn't attach normally, so I guess that's
not surprising?) -- I still get a kernel panic.

`disable pckbd` causes lines in dmesg like:

  pms1: disable error
  ...
  pckbc: command timeout
  pms1: disable error

and so on. The keyboard is non-operational at that point and, since I
(temporarily at least) don't have another machine, I don't have any way of
executing wsconsctl to see if it panics. I can try tomorrow if it would be
helpful?

The patch you provided works (thanks!):

  $ doas wsconsctl keyboard.encoding
  keyboard.encoding=unknown_0
  $ doas wsconsctl keyboard.encoding=uk
  wsconsctl: WSKBDIO_SETENCODING: Bad address
  $ doas wsconsctl keyboard.encoding=gb
  wsconsctl: gb: not a valid encoding

I realise as I type the above that I've never had a need to configure a
keyboard encoding before. I guess the "unknown_0" is unexpected? It may also
be significant that "uk" (which I *guess* is the keyboard's encoding) borks
in a different way than "gb"?
