It's harmless.
The driver is attempting to see if the NIC is generating an interrupt which isn't
actually interrupting the CPU. If so, it prints this out and calls the ISR "by hand".
It's a sneaky trick of Mr Becker's which is designed to allow the NIC to limp along
even if the interrupts aren't working. It will work nicely on uniprocessor and on SMP
but will be occasionally fooled into thinking that a perfectly good NIC is broken on
SMP.
