Yes. The kernel version is 2.2.14.

Thanks.

I don't think the 2.2.x kernel can set up IRQs correctly. Can you try 
2.4.x kernel first ?

I can't help you then. 2.2 just won't do the right things for IRQs.

We're going to have to get linuxbios to set this stuff up.

I made a first stab but ran out of time, will have to try again later.

2.2 was o.k. with an SMP kernel, and an MP table in LinuxBIOS.  The
other cases it failed with.  We were just happy when we could load 2.2
and we quickly switched to 2.3.x.  The 2.4.x kernel code for assigning 
interrupts from irqs is not to bad, if you want to look at putting
it into LinuxBIOS to support your 2.2.x kernel....

The interesting variant which is coming up is MSI.  Interrupts
over the pci bus, as specified in pci 2.3, pci-x 2.0 and pci-express.

The interrupt story keeps getting more complicated, not less...

I was able to get 2.2 IRQs to work with the stpc.  Look at
src/mainboard/stpc/consumer2/mainboard.c.

The rest of the file is code to avoid a kernel patch for a non-supported
router (in 2.4).
