Hi,
When I updated to Linux Kernel 3.3.5 on my mid-2010 Aluminum Unibody Mac
Mini,
its built-in wireless was no longer recognized:
03:00.0 Network controller [0280]: Broadcom Corporation BCM43224
802.11a/b/g/n [14e4:4353] (rev 01)

Capabilities: [160] Device Serial Number 54-70-4b-ff-ff-0c-60-33
Capabilities: [16c] Power Budgeting <?>
Kernel driver in use: brcmsmac
I tried kernel 3.3.0 with the same negative result.
When I reverted to 3.2.16, the chip was immediately recognized.
The driver in 3.3+ is loading the bcma module.
I've fine with running 3.2.16 for now.
Is this a known problem? A configuration error on my part?
Just let me know if you'd like me to try anything to help debug this
(possible) regression.

Arend,
Strangely, when I rebooted the box under 3.3.5 this time, the WiFi worked!
I will post again if it drops out.
For reference, here are the files you requested.

The kernel configurations you sent me look fine. I noticed you have
debugging enabled for bcma and brcmsmac so can you sent me a dmesg for
the 3.3 kernel. lspci should show bcma as the driver for the device.
Unfortunately, there is no lsbcma.

Thanks for the quick response.
I've not blacklisted bcma for either 3.2 or 3.3 kernels.
Yes, I built the kernels myself. The mac mini runs a Debian Mint 11.
The brcmsmac driver in 3.3 seems to have dependencies on bcma, It won't
load without it.
When I reverte to 3.2.16, I just unconfigured the bcma driver, so it
never built.
the kernel .config for 3.2 and 3.3 are attached.
Let me know if you need me to reboot the box with the 3.3 kernel and
post dmesg or other logs.

Any log on 3.3 kernel may help. Do you have bcma blacklisted in your
system? Do you have built the kernel yourself? Can you sent the .config
for both kernels?
