Just in case anyne might be interested, I have been trying to debug this
issue. It seems that pirq_find_routing_table() is not locating the
table in the range it is looking. I turned on debug trace and added
some other debug code. The PIRQ signature is not there in that range at
all. Without the table, the router is not identified. I also tried
forcing ACPI to be enabled, but that didn't seem to help.
Whether or not any of this matters in the end is a little unclear to me
at this point. I have experience with (c)PCI, but not on x86 hardware.
Is there an online resource that explains how the APIC is supposed to
work in a bit more detail? There aren't very many comments in the code
to go on.
Thanks.
