Description From 2005-05-11 02:10:52
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.
