I believe I was using a simialar card, and had a similar experience. I
would have wedge errors display to the consol and eventually the whole
system would hang. I looked up the wedge error message in the driver
code and it indicated that there may be some sort of hardware bug in these
cards. If you have your source tree loaded on your drive you can search
in the /usr/src/linux/net directory for the proper file I think.
