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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
