BCM43228 not working (no access points shown)

[Falco Preiseni]

Hi Rafał,

thanks for your efforts :) I tried out the wl driver on ArchLinux but it didn't
work either. However, on Debian the wl driver works with my card:

$ uname -a
Linux noname 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux

$ dmesg
[   97.463846] wl 0000:02:00.0: setting latency timer to 64
[   97.492386] INFO @wl_cfg80211_attach : Registered CFG80211 phy
[   97.493105] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller
5.100.82.112

On ArchLinux I noticed that there is always (for b43 and wl) the same error
(INVALID_DEVICE_REQUEST) in the dmesg output after the broadcom stuff:
[  587.974839] wl0: online cpus 1
[  587.975382] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller
6.30.223.248 (r487574)
[  587.983443] wl 0000:02:00.0 wlo1: renamed from wlan0
[  588.134778] AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:00.1
address=0x000000fdf80c0020 flags=0x0a00]

I found only one entry on google [1] with the same error and interestingly
enough that user has the same wifi card and laptop model (HP Elitebook 755 G2
with AMD processor). Unfortunately the given solution (add *intremap=off* as
kernel parameter) does not work for me :(

Howsoever: It's not a b43 problem. I don't know...

Regards,
Falco
