The SMP-HOWTO says that this "indicates a 'receive
checksum error'. This cannot be caused by Linux as the
APIC message checksumming part is completely in
hardware. It might be marginal hardware. As long as
you don't see any instability, they are not a problem -
APIC messages are retried until delivered."

Logging of these error messages dates back to 2.3.20

Might hafta look at the interrupt handling and 
write some baling wire and duct tape in C...
