Looking into the boot scripts, swap is enabled in /etc/rc.d/rc.sysinit. The 
next step is to start the serial ports, then load st if required and then 
usb-storage. It might be one of those that's causing the problem.

In the past, when I've had to track down boot time hangs, I've run the boot 
scripts with the -x flag, or placed strategic 'set -x'/'set +x' commands 
within the scripts to trace execution. I've not done it on a Linux system 
but the principle should be the same. You might try putting a set -x in 
rc.sysinit just before it sets up swap to see what command is issued before 
the hang.

BTW, my SMP systems are Supermicros. The one I'm using for my current tests 
is an X5DPL-8GM. It doesn't have SCSI or hardware RAID. I don't enable sound 
or USB - it's a server and doesn't require either.
