This is both cases. I made another one and here, I can give more
details:
Network manager is trying to list APs and fails until time
1379858724.386569
The The first "iwlist wlan0 scan" is done juste after the log line
(1379858738.682054). It lists the APs in range in the console but
not in the Network Manager ui.
The second "iwlist wlan0 scan" is done at time 1379858739.802067
and APs are being listed in the console and in the Network Manager
UI.
After that, NM will connect to the acces point with SSID "Maison".
It also looks like the listing in Network Manager comes between the
moment "iwlist wlan0 scan" is run for the second time and the
moment is shows its output on the console.
Detlev.

* [PATCH] staging: vt6656: [BUG] main_usb.c oops on device_close move flag earlier.
From: Malcolm Priestley @ 2013-09-22 18:48 UTC (permalink / raw)
To: gregkh; +Cc: linux-wireless
The vt6656 is prone to resetting on the usb bus.
It seems there is a race condition and wpa supplicant is
trying to open the device via iw_handlers before its actually
closed at a stage that the buffers are being removed.
The device is longer considered open when the
buffers are being removed. So move ~DEVICE_FLAGS_OPENED
flag to before freeing the device buffers.

From: Malcolm Priestley @ 2013-09-22 19:15 UTC (permalink / raw)
To: gregkh; +Cc: linux-wireless
There seems to be race condition that the device is ndo_start_xmit
at a point where the device is closing and apTD is NULL resulting
in dead lock.
Add a NULL check to apTD and return NULL to calling functions.
This is more likely on 64 bit systems.

* p54usb raspberry pi no wlan0 device
From: the_force @ 2013-09-22 20:05 UTC (permalink / raw)
To: linux-wireless
Hi Folks,
i want to use an Corega WLUSB2GTST USB adapter on my Raspberry Pi linux device. I used fwextract utility with the driver file (Windows 2000 driver, nobyteswap option). So i got these 2 files:
cgwlusb200.arm
cgwlusb201.arm
I have copied these files (i tried cgwlusb200.arm also cgwlusb201.arm) to the following location on my Raspberry Pi:
/lib/firmware/isl3887usb
/lib/modules/3.6.11+/kernel/drivers/net/wireless/isl3887usb
After doing a modprobe p54usb, the module seems to load fine:

Everything looks fine - but no wlan0 device will be created :-( The led on the stick will not turn on, so i think i have a driver problem.
How can i debug / solve this problem?!?

* [PATCH V3] wireless: rtlwifi: Replace variable with a break
From: Peter Senna Tschudin @ 2013-09-22 20:22 UTC (permalink / raw)
To: Larry.Finger
Cc: joe, sergei.shtylyov, chaoming_li, linville, linux-wireless,
netdev, linux-kernel, kernel-janitors, Peter Senna Tschudin
This patch removes the variable continual, and change the while loop
to break when efuse_data == 0xFF.
Tested by compilation only.
CC: Joe Perches <joe@perches.com>
Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com>

Changes from V2:
- Fix typo in the subject
- Fix indentation
Changes from V1:
- Fix the indetation
- Remove remaining } from removed else
Please ignore the patch:
[PATCH 12/19] wireless: Change variable type to bool
And apply this one instead.
The variable continual was declared as int, but was used as bool. I
sent previous patch changing the variable type to bool, but Joe Perches
proposed that removing the variable and adding a break would be better.

I think I found the driver. It's a generic firmware, but it's really old (pre 2.7.0.0).
You should go to <http://wireless.kernel.org/en/users/Drivers/p54> and get the latest
one from there for your device (isl3887usb > 2.6.29).

This should be the right location and filename for the firmware.

I can't find this device-id in the p54u_table. Did you add it manually?

Is this output cropped? p54usb announces which firmware file it requests.
Furthermore, In your case you should have seen something like this in dmesg:
"wrong firmware, please get a firmware for "isl3887usb" and try again."

Looks like the firmware on the device crashed. You should physically disconnect and
reconnect the stick before trying again.

* [PATCH v4 00/16] wcn36xx: mac80211 driver for Qualcomm WCN3660/WCN3680 hardware
From: Eugene Krasnikov @ 2013-09-22 22:41 UTC (permalink / raw)
To: linux-wireless; +Cc: wcn36xx, Eugene Krasnikov
This is a mac80211 driver for Qualcomm WCN3660/WCN3680 devices. So
far WCN3660/WCN3680 is available only on MSM platform.
While waiting for a merge window to be opened a lot of changes were added to wcn36xx. The main goal of changes was to move all properties from wcn36xx struct to wcn36xx_vif and wcn36xx_sta structs.
To make review easier the driver sent in several patches, one patch per file, but after
review it will be sent as one big file.
Firmware can be found here:
https://www.codeaurora.org/cgit/external/hisense/platform/vendor/qcom-opensource/wlan/prima/tree/firmware_bin?h=8130_CS
Wiki page is available here:
http://wireless.kernel.org/en/users/Drivers/wcn36xx
A lot people made a contribution to this driver. Her is the list in
alphabetical order:
