there is no udevd module.. udevd is a normal process and if you kill
it, you change nothing...

you may try to upgrade udev to the FC3-updates version, which will
also be in RHEL4.

I did unload udev module, sorry for mistype to udevd. 

As I know udev-040 may fix this problem. 

Comment 3 Harald Hoyer 2004-11-18 05:48:12 EST
there is no udev module also

SOrry, recheck it. It is udevd daemon. After killed the daemon, 
hotplug can load the firmware correclty.

Comment 6 Harald Hoyer 2004-11-29 06:10:46 EST
are you sure you have to kill the udevd daemon??

Try to just reload the module

# modprobe ipw2100
   Failed with firmware can't be found.
# modprobe -r ipw2100; modprobe ipw2100

Did this test again on RHEL40-Pre-RC2. Now the 1.0.0 2100 driver can 
load firmware successfully without needing to unload udev module.
So this bug seems to have been fixed.
