Hi,
I caught a complaint by Linux 2.2.19 which has a 3C509B that it ran into
an infinite loop in its IRQ handler. Driver bug?
Thanks in advance,

It means the card kept having work left to do - eg because it was under
extreme load at that point. Its not neccessarily a bug - did the box then
recover ?

Yes, it did. The LAN (twisted pair cabling, 16 bit prefix) contains
several hundred Windows workstations alongside some Linux boxes (in the
same collision domain, that is), so the machine may have been under
severe broadcast load as is common for Windows machines to toss out.
