12.2 M3 Broadcom driver troubles

English Install/Boot/Login
1

I installed 12.2 M3 to bug hunt, and have some weird braodcom driver problems. I have a BCM43224 wireless card. It works with the brcmsmac driver. The live CD install kept trying to load the b43 driver which doesn’t work with this card. I blacklisted b43, and modprobed brcmsmac to get it working. The problem is when I reboot, I have to unload and reload (modprobe) the driver for the card to work. Is this a 12.2 bug? Earlier versions all loaded brcmsmac by default. This is after rebooting and loading/unloading brcmsmac:

This is after reboot:

The card shows the brcmsmac driver in use, so why doesn’t the card work after rebooting?[/size][/size]

What does dmesg show before you unload and reload brcmsmac?

With kernel 3.3, the 43224 does work with bcma and b43, but you probably don’t
have the firmware installed.
