noapic only prevents that hardware interrupts are rerouted through the
io apic.
The inter processor interrupts still use the apic bus, and it's
impossible to use SMP without IPIs.

It could be a hardware problem, or the board uses an unusal io apic
that's not properly handled.
If you boot without noapic, are there any unusual message in the boot
log?
Perhaps
MP-BIOS bug
unknown io apic
etc.
