Hi there,
I'm running Gentoo with a x86_64 3.6.6 kernel on a Dell latitude 6420. I
have a Broadcom 43288 device which is detected by bcma but nothing
further happens.
Here is the device:
lspci -vnn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Corporation BCM43228
802.11a/b/g/n [14e4:4359]
Subsystem: Dell Wireless 1530 Half-size Mini PCIe Card
[1028:0011]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at e2d00000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [40] Power Management version 3
Capabilities: [58] Vendor Specific Information: Len=78 <?>
Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [d0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [13c] Virtual Channel
Capabilities: [160] Device Serial Number 00-00-f5-ff-ff-39-84-4b
Capabilities: [16c] Power Budgeting <?>
Kernel driver in use: bcma-pci-bridge
Here is the output from BCMA:

The b43 driver loads (ie prints 'Broadcom 43xx driver loaded [ Features:
PMNLS ]') but then nothing else happens (I'd expect to see some kind of
phy detection for example). It's possible that I could be missing a
kernel config option but I'm fairly certain I'm not.
I realise that the 43228 device is marked as untested in the table on
linux-wireless but I was hoping that it would work with b43.
I've added various debug instrumentation to b43 to try to establish
what's going on but it seems that the only activity is from b43_init().
There is no request to set up the core or load ucode etc.
I'd rather not use the closed source sta driver and the soft/full MAC
drivers don't support this device AFAIK (the STA driver loads and
detects the device but I constantly get crashes in the 80211 sub-sys
when the interface gets accessed).
I'd appreciate any thoughts anyone might have about how I can proceed
with getting wifi working with b43. I've tried a lot of things.
Hopefully there's something I've missed. All help / comments appreciated.
Many thanks,
-- Matt
