Multiple IRQs for PCI interrupt

Can anybody shed any light on the following panic :
	Multiple IRQs for PCI interrupt 0.31.INTA: 18 and 16

Looking at the code this comes from mptable_pci_route_interrupt_handler()
in i386/i386/mptable.c.  This message comes when I try to put 7.0 on
a box that was running 6.2.  Comparing 6.2 and 7.0, it looks like I 
might have the same problem if I turned on INVARIANTS in 6.2.  

For now I have ifdefed out this check, but I would really like to
understand the issue.
