This machine can be configured as a 4-8-16-32 way system.
When I disable 16 CPUs, it freezes while loading xen, before
it starts showing the boot output for the Domain0 linux.

You said you were able to boot the same box as a 16-way SMP?
How did you do that exactly? Did you pass maxcpus=16 on the
command line or did you disable the CPUs somehow?

And when you say the box hangs... Can you eventually ping
it?
