That v2.2.x did not print any messages for this error. It was happening,
just not being reported. Many BP6 boards get errors like this.

If you are overclocking this tends to make the errors happen more often.

I have only been running 2.4.0-test12 for a short while (must upgrade to
2.4.0 final now) but have not seen any APIC errors (yet - fingers crossed)

Actually just posted it in comp.os.linux.hardware....
I'm curious to know if anyone knows what this is. It doesn't seem to be
a major problem,
because the system is otherwise stable.

Sounds like the famous broken voltage regulator problem.
Is your board a Rev. 1.1? (Look at the side of the 2nd ISA slot).
All Rev. 1.1 boards have a broken voltage regulator resulting in
a (more or less) fluctuating CPU core voltage.
In my case it fluctuated so much that the board was unstable.
Therefore I requested a RMA and got a new board.

Regards,

Marcel
