Hello,
There is a BCM4312 wifi card bundled in my laptop.
Last week I used the everything branch of wireless-2.6 subtree and the patch of larry finger (from this email
:http://www.mail-archive.com/bcm43xx-dev@xxxxxxxxxxxxxxxx/msg05586.html) and with commit
755a957d407c3fcac58360d9309b1664078ac15d.
With this couple (patch + commit level) i was able to get my card working.
Here is the information about this card with lspci :
30:00.0 0280: 14e4:4312 (rev 02)
Subsystem: 103c:1371
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 21
Region 0: Memory at c8000000 (64-bit, non-prefetchable) [size=16K]
I have some warning:
[ 36.199157] WARNING: at drivers/ssb/main.c:883 ssb_tmslow_reject_bitmask()
[ 36.199168] [<f8ad48cb>] ssb_tmslow_reject_bitmask+0x4b/0x60 [ssb]
[ 36.199179] [<f8ad5201>] ssb_device_is_enabled+0x11/0x40 [ssb]
As I have understood they are harmless and a couple of second later I have this message :
[ 74.142529] b43-phy0 debug: Loading firmware version 351.126 (2006-07-29 05:54:02)

[ 75.281746] ADDRCONF(NETDEV_UP): wlan0_rename: link is not ready
And finaly after logging through GDM, network manager manage to set the card so everything is ok.
The systems is quite stable, I use it since one week and there is no errors as I can recall.
In fact there is one problem: suspend to ram. After resuming from suspend to ram, i have the b43 constantly running and
taking 50% at least of the CPU (as reported by top) and no network connection.
Even after killing NetworkManager, this "process" is still eating all the CPU.
It keeps saying :

I tried a couple of time (I often suspend to ram my laptop once a day : before going to bed) to remove the module :
rmmod b43
But it finish like this :

Yesterday I fetched a more recent version of the everything branch and built a kernel with the latest patch from larry
finger, I've planned to test it this afternoon, I'll publish then my results with this.
