>Description:
My ath(4) card (Netgear WG511T PCMCIA) is not working at all when I insert it before switching my laptop on. Instead systat/top show high load with interrupts. I also attached kernel messages appearing (see part of dmesg output). In this state you can also cause a panic when you eject the card.

I can use my wireless LAN with ath(4) perfectly (perhaps associating a bit slow, but at least it works) when inserting it after login appears.


Here some additional info (while the card is not working). In case you need more contact me.


dmesg (small part):
ath0: device timeout
ath0: ath_reset: unable to reset hardware; hal status 3231587658
ath0: ath_chan_set: unable to reset channel 6 (2437 Mhz, flags 0x480 hal flags 0xc0)
ath0: ath_chan_set: unable to reset channel 11 (2462 Mhz, flags 0x480 hal flags 0xc0)


from systat:
