SubjectRe: 3c509 + sb16 bug
Perhaps it's cold comfort, but I found long ago that
3c509 and SB don't mix too well, at least in Linux.

ISA devices are somewhat dumb, switching one
of the cards for a PCI version does the trick here.

SB128, SBlive work fine, or you might want to go
to a 10/100 pci ethernet card.

Just my $.02
