Re: Tyan Tiger 100 (S1832) IO-APIC Problems

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.
