Still the same problem with 2.6.23.1:

root@OpenWrt:/# ifconfig eth1 up
eth1: resetting device...
eth1: uploading firmware...
eth1: firmware version: 1.0.4.3
eth1: firmware upload complete
eth1: interface reset complete

root@OpenWrt:/# iwlist eth1 scanning

Sometimes I even get this weird stuff:

root@OpenWrt:/# ifconfig eth1 up
eth1: resetting device...
eth1: uploading firmware...
eth1: firmware version: 1.0.4.3
eth1: firmware upload complete
eth1: no 'reset complete' IRQ seen - retrying
eth1: no 'reset complete' IRQ seen - retrying
eth1: interface reset failure
prism54: Your card/socket may be faulty, or IRQ line too busy :(
ifconfig: SIOCSIFFLAGS: Timer expired


Thanks for looking into it, much appreciated.
