Hi, I have been trying to test the new kmod-compat-wireless rpms on a newly
installed rhel6.3 laptop and can not get the firmware to load. I have the
firmware files extracted and in the /lib/firmware/b43 folder. The kmod
loads but says the firmware is missing. Here is the info from dmesg:

Hardware is a new mid-2012 macbook pro. Any suggestions? Is there a way to
see where it is looking for the firmware files? Do you need more info?
Thanks,

Hi Roy,
Thanks for the info.
Dmesg above has already told you where it's looking for the firmware:
b43-phy0 ERROR: Firmware file "b43/ucode29_mimo.fw" not found
so that would be /lib/firmware/b43/ucode29_mimo.fw
A common trait emerging seems to relate to firmware failing to load, and
I believe the new v3.5 compat-wireless branch uses a new firmware loader
so I suspect some incompatibility somewhere along these lines. I'll try
to look into this next week but it's difficult without hardware to test.
With the driver loaded, do you see any firmware related modules loaded?
For example, any output from:
/sbin/lsmod | grep firmware
and can you show us:
/sbin/lsmod | grep b43
Thanks.
