Yes, this sounds about right. It's the prism54 driver, as Russell identified in another reply.

Since the card is a PCMCIA prism3 card in a cardbus adaptor, any interrupt sent to yenta will be destined for the eth0 wireless card. It's not really a problem, I was just putting the driver under duress because I had the firewire controller heavily loaded.
Unfortunately these nForce2 boards crammed full of on-board hardware typically assign at least firewire and the AGP slot IRQ 19, and the PCI slot I've got the cardbus adaptor in is also sharing this IRQ line. I can't really do anything about it, I'm afraid to say.
Thanks for the reply Grzegorz.
