These messages are informational only, they don't represent a
problem when taken alone.
More info:
Several of these messages have been "fixed"
in later versions of 2.4 and eliminated in Linux 2.6.
They are informational only and don't affect the operations of Linux.
They come from Linux having a known-valid list of IO APIC devices
and that list not being updated very often (hence the message
removal in Linux 2.6).
