i386 SMP boot freezing

I have an old compaq proliant with 2 Pentium-II 400, I wanted to test
DragonFlyBSD on it.
The GENERIC kernel works fine with one cpu. I compiled the
GENERIC+SMP+APIC_IO, and boot hangs with :
APIC_IO: Testing 8254 interrupt delivery
APIC_IO: Broken MP table detected: 8254 is not connected to IOAPIC #0
intpin2
APIC_IO: routing 8254 via 8259 and IOAPIC #0 intpin 0
nothing happens after these three lines. Does that means APIC won't work on
this system ? or is this a kernel bug ?
I've noticed in the GENERIC config file above SMP options, that on some
systems, SMP with no APIC_IO might be working. I tested it, it boots
correctly, a SMP motherboard is detected, cpu0 is detected but not cpu1.
Thanks ! :)
