Any chance to build and run a more recent kernel on it, to see
whether this issue still occurs? The latest APIC code is at:

http://people.redhat.com/mingo/tip.git/README

And i suspect you should pick up the Knoppix .config and build with
that to reproduce this issue. A digital picture of the panic would
be useful as well.
