about IO-APIC
Hardware : ms6368
Distro: Suse 7.1 ( Ok, rather obsolete)
Kernel still "out of the box"
( I need a development system, not developing kernels)
I get a message you might be interested about the IO-APIC in
the boot messages. Perhaps it has also got to influence on
my problem with an ISA serial multiport card wich I cant get
working properly. This card is an Moxa CI123 dual 16550A,
using its dedicated driver mxser.
cat /proc/interrupts |nicetxt

11: IO-APIC-level eth1

NMI: big count
LOC: big count
ERR: 0
I hope you can do something with this.
