The code that's being run does the following:
1. Finds all network interfaces.
2. Finds all CDROM, floppy, disk and network devices that might be
needed for installation.
3. Finds all partitions on the disks to register.
I'd guess it's hanging on a syscall somewhere, but there really isn't
much debugging output in usr.sbin/sysinstall/devices.c to know where,
unless the kernel has printed some errors to the debug console.
