Subject2.4.11 APIC problems
From
Date
Hadware is a Netvista PIII-850, single processor
I have priviously (2.4.10 and below) been able to use this machine with
IO-APIC turned on. I turned on Local APIC and IO-APIC in 2.4.11 and all
I got on boot was an endless stream of error messages that look like
this:
APIC error on CPU0: 08(08)

Here is the output from the serial console. I didn't see the previously
mention error message in the serial console though. Where I would have
expected to see it, all I got was random garbage.
