How reproducible:

Steps to Reproduce:
1. Put ipw2100-1.3 firware to /lib/firmware

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.

Comment 2 Crystal Xiong 2004-11-18 02:50:00 UTC
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 10:48:12 UTC
there is no udev module also

Comment 4 Crystal Xiong 2004-11-19 03:19:46 UTC
SOrry, recheck it. It is udevd daemon. After killed the daemon, 
hotplug can load the firmware correclty.

Comment 6 Harald Hoyer 2004-11-29 11:10:46 UTC
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

Comment 7 Crystal Xiong 2004-12-27 10:18:00 UTC
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.

there is no udev module...
