Hi,
I posted this a few days ago against 3.6-rc7, but got no response.
http://marc.info/?l=linux-wireless&m=134875589522742&w=2
Tested again today against 3.6 stable, and still triggering kernel bug.
Attached updated kernel trace from syslog.
Best,
Jasmine Hassan

I also have to install dell's bluetooth package for an updated btusb +

Since that's the closed proprietary driver, there's pretty much nothing
anyone here can do about it, since we don't have the source code. The
ball is in Broadcom's court.

I am on Gentoo and using wpasupplicant with Broadcom BCM4727 802.11 Hybrid
Wireless Controller 5.100.82.112.
Everything works perfect in 3,5,4
Upgrading to 3,6,0 stable gives same bug as to you.
Only thing chanced is kernel.
So I believe that's kernel busines

I think your device is not BCM4727 so can you give me 'lspci -v' output.
The broadcom-sta package is provided by the distros and maintained by
Broadcom as it is a out-of-tree driver. That means it needs to keep up
with the latest kernels, but it is lagging. Basically, this is the major
disadvantage of *not* doing driver development upstream.
Issue with broadcom-sta package can be sent to:
linux-wlan-client-support-list@broadcom.com

Arend

(resent to list as plain text)
Hi,
@Dan, yes. Though it's mixed/propietary, it would be great if at least
Broadcom would publish specifications for the PHY (LCN40 rev 3) to
allow others who are interested (as Rafał Miłecki) to develop
open-source drivers.
Luckily this time, the issue was in the part of the driver where
source is available.
--
Frank Vanderham, maintainer of the same driver (wireless-bcm43142) in
the AUR, turned my attention to changes suggested by another user
(andreyv) on broadcom-wl, also in the AUR.
https://aur.archlinux.org/packages.php?ID=19514&comments=all
He noticed warnings while compiling the module against kernel 3.6.2:
aur-broadcom-wl/src/src/wl/
sys/wl_cfg80211.c:1647:2: warning: initialization from incompatible
pointer type [enabled by default]
aur-broadcom-wl/src/src/wl/sys/wl_cfg80211.c:1647:2: warning: (near
initialization for 'wl_cfg80211_ops.scan') [enabled by default]
And noted:
---
In Linux's <net/cfg80211.h> we see
int (*scan)(struct wiphy *wiphy,
struct cfg80211_scan_request *request);
but in the module we have
static s32 wl_cfg80211_scan(struct wiphy *wiphy, struct net_device *ndev,
struct cfg80211_scan_request *request);
---
Surely, doing a diff between 3.5.0 and 3.6.0
headers/include/net/cfg80211.h, one notices that net_device was moved
to wireless_dev, and subsequently the (second) parameter to
cfg80211_scan was dropped.
Looking at commits affecting drivers/net/wireless/brcm80211/brcmfmac/
from March onwards, one finds:
---
commit fd0142844efa85d89017c89227a0f03de1eee327
Author: Johannes Berg <johannes.berg@intel.com>
Date: Mon Jun 18 19:17:03 2012 +0200
nl80211: move scan API to wdev
The new P2P Device will have to be able to scan for
P2P search, so move scanning to use struct wireless_dev
instead of struct net_device.
---
Adapt a patch (attached) using LINUX_VERSION_CODE conditionals, as to
not break support for pre-3.6 kernels, and problem solved.
However, scan results seem quite limited. That is, discovered BSSID's
are noticeably fewer compared to results on 3.2.x-3.5.x, either via
`/sbin/iwlist wlan1 scanning`, or networkmanager. Only 3-5 are show by
iwlist, sometimes none, and network manager lists 6 at most.
Same driver on 3.5 (or prior) quickly picks up at least 15 BSSIDs.
Is there something obviously wrong with the patch?
Best,
Jasmine

Description: nl80211: move scan API to wdev
based on linux.wireless commit fd0142844efa85d89017c89227a0f03de1eee327
by Johannes Berg <johannes.berg@intel.com>
.
The new P2P Device will have to be able to scan for P2P search, so move
scanning to use struct wireless_dev instead of struct net_device.

I take that back. Limited scanning was due to having laptop's lid
closed (and working on an external LED) while testing. Obviously, the
wifi card's antennae are in the bezel of the screen (doh).
Scanning actually seems even better now, in 3.6.x :)
Best,
Jasmine
