Hello,
I'm running a RedHat 6.2 (kernel 2.2.14) on a quite "old" box and I get
the following message at boot time:
ENABLING IO-APIC IRQs
... changing IO-APIC physical APIC ID to 16
Kernel panic: could not set ID
when I boot with the "noapic" flag, everything is ok.
I think that may come from the board being "not standard", but I only
found references to a "black/white lists" without any link/location to
find these lists.
The io_apic.c code seems to tell that the list are "internal" to that
file?
The board is an HP Vectra XW PC Workstation with bi-Pentium Pro 200, an
on-board aic7880 scsi controller
Here is the /var/log/dmesg file (with kernel booted with "noapic") that
may tell more about it:

To do it short (?) ... does anyone know:
1. where to find the/some board-lists (maybe there already exists a
"pirq=??" line for that one ??)
2. where to find some "background" info about these IO-APIC (I'm not
sure to get the importance of having all the interrupts only on the
boot-CPU (?))
thanks.
