Description of problem:
When connecting to any wireless network using the Network Manager applet, my iBook G4 immediately locks up hard.
My motherboard has a Broadcom 4318 (airport) wireless device built in, so my initial response is to be suspicious of the b43 driver. I'm using the latest available firmware for the Broadcom chip.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot the computer.
2.Log in to desktop.
3.Give Network Manager wireless secrets.
Instead of connecting to my network, the computer crashes.
Instead of crashing, my computer should have connected to the network.

This problem doesn't appear to be present in the older 188.8.131.52-30.fc9.ppc
kernel. (I just rebooted into the older kernel, and the problem has gone away.)
Is this a kernel driver regression?
Not limited to ppc, also locked up a x86_64, a Gateway MX7120. Has a BCM4318
[AirForce One 54g] 802.11g Wireless LAN Controller, (rev 02)
Firmware was from broadcom-wl-184.108.40.206.tar.bz2
Locked it up real good, needed to hit power button. Caps lock blinks too, not
sure what that means.
Same here on x86_64 with a BCM4312 rev 01 (Dell Inspiron 1501). I get a kernel
panic as soon as my wireless starts to connect. This is not present with kernels
older than .6 .
Could you try -64 or later?
kernel-220.127.116.11-64.fc9.ppc appears to fix the problem for me. Thanks!
Also works here.
