Bug#463498: b43: Selects wrong driver?
Package: linux-2.6
Version: 2.6.24-1
Hi,
It seems that the kernel does not select the proper driver for me. When
booting a 2.6.22 (and .23) kernel, I see:
bcm43xx driver
PCI: Enabling device 0000:02:00.0 (0000 -> 0002)

low) -> IRQ 10

But this b43 driver doesn't seem to be working for me. I notice some
strange behaviours with this:
- After the "udev: renamed network interface wmaster0 to eth3" it hangs
for several seconds before doing something else. At that point
something prints "done" on the screen which doesn't come from the
kernel. (Manual modprobing b43 doesn't seem to cause this problem.)
- When looking at the interface list I see a "eth3" that doesn't
have wireless extentions, and a wlan0_rename that does. I
also have 1 more device than I should.
Reading http://linuxwireless.org/en/users/Drivers/b43 it says:
"4306 and 4309 cards with a MAC core revision of 4 or less should
also use b43legacy. [...] The kernel autoloader will automatically do
the right thing and load the correct driver for your device."
If I read the dmesg above right I have a 4306 with MAC core revision 3,
so I should use b43legacy. It seems to me that it's not doing the right
thing here.
So I've tried rmmod b43 and modprobe b43legacy but that doesn't seem to
be doing much.
