: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.
