b43 firmware loading maybe fixed

January 24, 2012 — BarryK
I don't have the hardware to test, but I might have found the solution.

The problem is that the firmware for the b43 module does not load for the 3.x kernels.

I examined the udev logs that peebee posted:
http://www.murga-linux.com/puppy/viewtopic.php?t=75209&start=150

Running "modinfo b43" told me that this is an 'ssb' device, and it seems that the appropriate kernel uevents are not getting replayed. This gave me the hint. I looked into /etc/rc.d/rc.sysinit and found a bug in version comparison -- a test for kernel versions under 2.6.24 is broken for 3.x kernels, causing 'ssb' uevent replay not to occur.

Fixed, Woof commit here:

Can this be tested without a new build?

Hi Barry It would be great to test this - do I have to wait until somebody creates a new puppy using the new woof or is there something I can change in an existing k3 build like racy5.2.2 or slacko5.3.1.3 ?? Thanks peebee

Tested - it works - b43 is back
