Subject: BCM4306 (rev 5) Problem with firmware loading since kernel 3.4
Date: Thu, 19 Jul 2012 10:52:08 +0200 [thread overview]
Message-ID: <20120719085208.GA17532@dirichlet.Morel> (raw)
Hello,
I'm using the card:
03:03.0 0280: 14e4:4320 (rev 03)
Since kernel 3.4 b43 has problems with loading the firmware for me.
Bisecting gave
# bad: [6b6fa5868eec26bdc6a83543cebb8cf832a2645a] b43: Load firmware from a work queue and not from the probe routine
git bisect bad 6b6fa5868eec26bdc6a83543cebb8cf832a2645a
# good: [a3ea2c76b193be5794e0de6aff66e14c21b904f8] b43legacy: Load firmware from work queue instead of from probe routine
git bisect good a3ea2c76b193be5794e0de6aff66e14c21b904f8
With the problematic kernel dmesg tells me:
[ 1.230562] b43-phy0: Broadcom 4306 WLAN found (core revision 5)
[ 1.363845] b43-phy0 debug: Found PHY: Analog 2, Type 2, Revision 2
[ 1.363866] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2
[ 61.944937] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found
[ 61.944942] b43-phy0 ERROR: Firmware file "b43-open/ucode5.fw" not found
[ 61.944945] b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.
Surprisingly, I could get the driver to load the firmware by including
b43/ucode5.fw in the kernel. Furthermore it seems to be able to load
other firmware from /lib/firmware. Now (actually this output is from
the current kernel from git) dmesg says:

The delay of 60 seconds is kind of inconvenient...
Do you have an idea what could be the problem or give me some hints how
to debug it?
Regards, Felix
