execute `iwconfig ethX mode auto;modprobe -r ipw2200;modprobe ipw2200` in one time. On T40(2200BG)+SuSE9.3(2.6.11-20a), system hung up, response lost, cut off power is the only solution. On Compaq(2915ABG)+FC3(2.6.9-1.667), system hung up for 10s, then recover to be operated give some messege about IRQ(dmesg in attachment), but ipw2200 module can't be load any more, unless reboot the system. Driver 1.0.2 have the same problem. I don't know if ipw2200 support "iwconfig eth1 mode auto", but it didn't give out error when exec it individually. If exec the 3 commands one by one, there are no exception. It looks as if they cann't be executed in a tiny interval.
