atheros - Linksys WPC55AG causes system hangs periodically

[George]

Hello,

I've been having issues with a PCMCIA based atheros card (Linksys 
WPC55AG [ver 1.2]) where after some time the device causes the system to 
stop responding until I pop the card out.  At that point I get the 
following error messages:

ath0: ath_reset: unable to reset hardware; hal status 3

I'm using the card on a Dell Latitude D600, and don't seem to have an 
issue with other PCMCIA cards.

I'm curious if others have experienced the same issue before?

Regards,
 George
