I'm having symptoms similar to what Wayne described in his 'wep problems' posting.
I have multiple Prism2.5 cards running hostap_pci source from about 2 weeks ago. When I enable WEP on the cards I get either a kernel panic or a message streaming across the console that the transmit queue is full. I have tried this on firmware versions 1.3.4, 1.3.5 and 1.4.9.
I tried WEP with a single radio card in the system and it did not panic. When I inserted another card, but only enabled WEP on one of the two, the system paniced. I've also tried changing the hostencypt and decrypt settings, not joy. The kernel is 2.4.19-rc1.
I notice in /var/log/debug that when I enable WEP it logs (this system had three cards):
