RequestIRQ: Resource in use

Hi,

using Debian and kernel 2.4.2 I had hostap working nicely with a D-Link
DWL-650 card and a Ricoh-based PCI->PCMCIA bridge. Now I've moved everything
to a new machine, using the same bridge and card, the same kernel (and
kernel config) and the same hostap version but it's not working any more.
Inserting the card results in hostap reporting "RequestIRQ: Resource in use"
and the freeze or the cardmgr crash. (see dump). Anyone know what to do?
