Bizarre observation:

boot.cfg:

menu=Boot normally:rndseed /var/db/entropy-file;consdev com0,57600;boot
menu=Boot single user:rndseed /var/db/entropy-file;consdev com0,57600;boot -s
menu=Boot Xen:rndseed /var/db/entropy-file;consdev com0,57600;load /netbsd-XEN3_DOM0 console=com1 com1=57600,8n1,0x3f8;multiboot /xen-debug.gz dom0_mem=1024M
menu=Drop to boot prompt:prompt
default=3
timeout=5
clear=1


If I press "1", I still get "loading /netbsd-XEN3_DOM0" and a spontaneous
reboot. I need to press "2", then ctrl-D in single user for the equivalent
of "1".
