Nothing really. When it works with noapic basically means your SMP
mainboard has a faulty IO-APIC, which is used by linux to set up IRQ in
an alternative way. If it's not configured correctly (mostly because of
a faulty bios) linux can't get it's IRQs correct without the noapic
option (where it will bypass the io-apic, and use the normal interrupt
controller).

My guess is IPv6 didn't work either, as your ethernet didn't work at
all.
