I was able to boot manually using
boot hd:2,\:tbxi
At that point I changed the /boot/loader.conf removing the kern.smp.disabled statement and than
rebooting. I was expecting it to drop to the OF prompt but it auto-booted just fine.
But now I have the same issues as when I was installing earlier. So seems like I have to keep the SMP kernel disabled.
dmesg shows that it saw two CPUs, but when using top, only one is seen (with SMP kernel disabled)
I am going to reboot with SMP disabled, until it is safe to enable it.
Next steps will be getting packages installed from ports.
cheers,
mehul
