Description Clark Tompsett 2010-05-20 13:18:03 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.4) Gecko/20100513 SUSE/3.6.4-1.11 Firefox/3.6.4

Clean install of factory on HP 311 with bcm4312 wireless chip.  Installed the firmware for b43.  Using the default kernel, drivers ssb and b43 load and wireless is working (2.6.34 kernel).  If you try to boot with the desktop kernel, the system hangs during boot while trying to load ssb.  

Reproducible: Always

Steps to Reproduce:
1. install factory on computer with bcm4312 wireless chip.
2.install the firmware
3. boot default kernel
4. repeat with desktop kernel
Actual Results:  
default kernel works.
desktop kernel locks up during boot.

Expected Results:  
the desktop kernel should boot with b43 enabled.

The wl drive will work with the desktop kernel, but using the b43 drive is recommended.

Issue is in the build differences between default and desktop kernels.

Hrm. I'm unable to reproduce this on my system with 2.6.34-8-desktop.

You can blacklist the module by adding a file, /etc/modprobe.d/b43-blacklist.conf that contains "blacklist b43"

I'd like to try to capture the crash, though.

Once you've blacklisted the module, boot into the desktop kernel. Then drop to console, run "klogconsole -r 0 -l 8" and then "modprobe b43". A digital photo is an easy way to capture it.

With the update to sysvinit from today, default will load b43 but desktop still fails with b43.

Comment 5 Clark Tompsett 2010-06-02 20:50:46 UTC

Additional information.  If you boot to level 3 in default kernel, you can modprobe b43 and it will load.  If you remove b43 and ssb from the blacklist then system hangs during boot.  If you boot to level 5 and attempt to modprobe in a terminal window system locks.

Problem appears to be the ssb driver that hangs system.

Since I reported this bug, what do you want me to do?
