We have some systems we are upgrading from FreeBSD 6.1 to FreeBSD 6.3.
These are Dell PowerEdge servers. The one I'm working on now is a 1950.
Under 6.1 it booted into SMP mode no problem. Under 6.3, with no changes
made in the BIOS settings, it does not. Here is the start of the dmesg:

And here's mptable up to the end of the CPU report:

After boot we have this:
kern.smp.maxcpus: 16
kern.smp.active: 0
kern.smp.disabled: 0
kern.smp.cpus: 1
kern.smp.forward_signal_enabled: 1
kern.smp.forward_roundrobin_enabled: 1
Any clues as to why SMP isn't starting? We've double checked that we
have both 'options SMP' and 'device apic' in the running kernel.
I've done a lot of googling, and have come up with nothing that seems
relevant to our situation. The most puzzling thing is that this worked
fine under 6.1 on these same machines
