Hi,

Just to make sure, I added the override for 2.

It should be OK to leave it as it is. You dont have another IRQ overrides? Perhaps there must be some for timer IRQ...
I don't know. In the mptable, I see an interrupt from 0x0 t0 0x2, but it is on bus 0x82, not bus 0. It doesn't make too much sense to me.

Looking at this made me remember that only PCI0 gets parsed by the kernel. I don't know why it skips the other root buses.

I was expecting to see entries for PCI1 and PCI2. When I run acpiexec I can see them with the namespace command.
They are now identical except for the headers and the addresses of the IOAPICs.
hmm this is strange... maybe we can leave there the only irq9 override for now. But you will need to put APIC to virtual wire mode maybe.
As long as I make it match the mptable, shouldn't it just work?
Right now I can't get it to match because the other busses are never parsed so those PRT entries are ignored.
