Description David Campbell 2007-08-02 01:17:46 UTC 
Description of problem:

The below exception is seen from the bcm43xx_mac80211 driver.
The wireless networking also doesn't seem to be working.
I have managed to get the wireless networking going with a ndiswrapper driver,
but not with this native driver, or with the older bcm43xx driver for that matter.

Version-Release number of selected component (if applicable):

2.6.22.1-41.fc7

How reproducible:

This driver needs firmware that has to be installed from an external location
into /lib/firmware, so I've included detail of what I'm doing.

Steps to Reproduce:

1. yum install bcm43xx-fwcutter
2. wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
3. tar xjvf broadcom-wl-4.80.53.0.tar.bz2
4. bcm43xx-fwcutter -w /lib/firmware broadcom-wl-4.80.53.0/kmod/wl_apsta.o
5. modprobe bcm43xx_mac80211

Actual results:

dmesg reports the following:

Expected results:

I would have expected no exception, and for the driver to work.

Additional info:
Comment 1 Kaare Fiedler Christiansen 2007-08-03 13:19:45 UTC 
The stack trace is a duplicate of bug #249483. Note that the stack trace is not
the reason for your wireless driver not working, however I can't say what is
wrong. For me the driver has worked since 2.6.22.1-33.fc7.
Comment 2 John W. Linville 2007-08-03 13:55:01 UTC 
Are you trying to bridge the wireless device?  I doubt if that will work.  
Could you remove the briding configuration and try again?
Comment 3 David Campbell 2007-08-03 23:52:42 UTC 
When you say bridge, do you mean bridging two ethernet connections, or something
else?  It isn't something I set up as far as I know.  Please tell me what to change.

/etc/sysconfig/network-scripts/ifcfg-wlan0 says:

TYPE=Wireless
DEVICE=wlan0
BOOTPROTO=none
HWADDR=00:0C:76:CA:71:33
ONBOOT=yes
MODE=Managed
Comment 4 John W. Linville 2007-08-30 22:02:52 UTC 
Please try the latest available F7 kernel.  Does the problem persist?
Comment 5 David Campbell 2007-08-31 01:14:38 UTC 
I can confirm that the stack trace no longer happens in the 2.6.22.4-65.fc7
kernel, but the error still does "b43-phy0 ERROR: bbatt(11) >= size of LO
array".  Also the drive usually doesn't connect, even 1 metre from the wireless
router.  I have managed to get it to connect on occasions...details below...

I have actually had wireless networking working with the bcm43xx_mac80211 driver
for the first time now, but getting it to connect is very flakey, even one metre
from the antenna, but once I manage to convince it to connect (when I've stopped
NetworkManager and rmmod'd the driver modules and then issued a modprobe
bcm43xx_mac80211 command and then restarted the NetworkManager), then it seems
stable.

On the odd occasion when the driver has actually connected I get this:

Comment 6 David Campbell 2007-09-26 23:48:32 UTC 
I no longer see this issue in later f7 kernel releases
