Thanks!

Do you have enough interrupts at all ? Because it leaves
only 4 interrupts of 16 for keyboard, real-time clock,
floppy, hard drive. Thank you for idea! I need only
8 ports :-) And it seems that cards like ASUS TX97
allow to do that.

I'm not sure about exactly that card, but in many cases switching
the card to promiscuous mode required by tcpdump is made through
reset. So perhaps your tcpdump just caused the second soft reset
of the card.
