Haven't tried that, as I say, it's a once a fortnight bug, so it may be a
little while
before I get round to finding out.

Well (and this is where it gets more interesting), some of the cards are
sharing IRQs (there aren't enough to go around....). When we have this
problem two interfaces on two separate cards usually go down together - two
interfaces that share the same IRQ. However, a third interface (which also
shares the same IRQ) seems to get along fine...
