# uname -a
Linux zd7000 2.6.32-5-686 #1 SMP Sun Sep 23 09:49:36 UTC 2012 i686 GNU/Linux

At boot time, I see several error messages about wlan (b43) (below)

wlan0 does not come up. ifup wlan0 fails.

# locate b43.ko
/lib/modules/2.6.32-5-686/kernel/drivers/net/wireless/b43/b43.ko
/lib/modules/2.6.32-5-686/updates/drivers/net/wireless/b43/b43.ko

The second one corresponds to the driver built from
compat-drivers-3.7.6-1

After boot, I log in and

# modprobe -r b43
# modprobe b43
# ifup wlan0

and wlan0 works!

It appears I have some disagreement between the compat-drivers-3.7.6-1 driver and the kernel. I have the correct headers (see below)

Just to be sure, I did a make uninstall, deleted the compat-drivers-3.7.6-1 directory, downloaded the tar.bz2 again, and repeated the build/install process. Same results.

In the build process, there was one warning about initialization removing qualifiers on a variable...

Any ideas?

After more investigation, it appears that some time is needed between loading the driver and ifup.

# ifdown wlan0 && modprobe -v -r b43 && modprobe -v b43 && ifup wlan0

fails.

# ifdown wlan0 && modprobe -v -r b43 && modprobe -v b43 && sleep 1 && 
ifup wlan0

works.

# uname -a
Linux zd7000 2.6.32-5-686 #1 SMP Sun Sep 23 09:49:36 UTC 2012 i686
GNU/Linux

At boot time, I see several error messages about wlan (b43) (below)

wlan0 does not come up. ifup wlan0 fails.

# locate b43.ko
/lib/modules/2.6.32-5-686/kernel/drivers/net/wireless/b43/b43.ko
/lib/modules/2.6.32-5-686/updates/drivers/net/wireless/b43/b43.ko

The second one corresponds to the driver built from
compat-drivers-3.7.6-1

After boot, I log in and

# modprobe -r b43
# modprobe b43
# ifup wlan0

and wlan0 works!

It appears I have some disagreement between the compat-drivers-3.7.6-1 driver and the kernel. I have the correct headers (see below)

Just to be sure, I did a make uninstall, deleted the compat-drivers-3.7.6-1 directory, downloaded the tar.bz2 again, and repeated the build/install process. Same results.

In the build process, there was one warning about initialization removing qualifiers on a variable...

Any ideas?

After more investigation, it appears that some time is needed between loading the driver and ifup.

# ifdown wlan0 && modprobe -v -r b43 && modprobe -v b43 && ifup wlan0

fails.

# ifdown wlan0 && modprobe -v -r b43 && modprobe -v b43 && sleep 1 && ifup
wlan0

works.

You probably have a copy of ssb or b43 in your initramfs, which gets loaded before the updated copy from compat-wireless becomes available. Update your initramfs to either contain the new version, or no version at all (in which case ssb and b43 will only be loaded after the root partition is accessible).
