Hi,
My keyboard fully stopped working in the latest HEAD.  There's no errors.

6 = ENXIO. Judging from sys/dev/misc/atkbd/atkbd_isa.c, that comes from 
atkbd_attach_unit(). Since atkbd_probe_unit() returned successfully, 
kbd_get_switch() isn't to blame. So it's either atkbd_probe(), 
atkbd_init() or kb_attach() which returns ENXIO. Now, you can either 
hook up a serial console, or add PMD[1] to atkbd_attach_unit().

This one should work though, unless it's the actual keyboard that's 
broken (can you see if it works in e.g. BIOS or the bootloader prompt?).

Cheers,
