:I don't have this set ...
:> ctl-alt-esc does eventually work if I boot -d and then 'cont', but
:> you have to realize that the system disables interrupts during early boot
:> so it won't see a ctl-alt-esc that early in the boot sequence.
:This might explain what is going on. The hang occurs in
:autoconf.c/configure() inside the call to spl0().
Inside spl0 means that a pending interrupt unmasked by spl0 is being
run and is causing the hang. Presumably it is related to the suspect
I recommend adding some diagnostic printf()'s to the interrupt service
routines for the device(s) in question, it might help you better diagnose
where the problem is occuring.
