Subject2.4.9 smp classic pentium boot message
I have a dual P120 board, dual socket 5 Intel Neptune chipset, the Asus
PCI/E-P54NP4.

I've had it for a few years, and up until recently the linux kernel hasn't
said anything alarming about it, and it ran just fine. With 2.4.9 it is
now barfing on PCI->IRQ mappings, something to do with nonexistant busses.
It's actually *working* just as before, I'm just wondering what these
messages actually mean, and if there is something I need to do to correct it.
