ADHOC issue with WL12xx driver

ADHOC issue with WL12xx driver

Hi,

We are encountering serious AD-HOC problems:
.	Commands are run successfully
.	The network is theoretically created
.	It is not visible for other devices and the DMESG show that an error
occurs and the firmware reboots

More info:
.	The box running Linux is the VAR SOM OM44
.	The operation system we are using is Ubuntu 12.04 LTS on the
3.4.0-1490-omap4 kernel. 
.	The processor is in the ARM architecture.
.	WiFi  card: Murata LBEH59XUHC.
.	WiFi driver: wl12xx, wlcore firmware wl127x-fw-5-sr.bin with Rev
6.3.10.0.135.
.	Network connection through the router is working. Network manager is
used to configure the connection.
.	Ad-hoc mode connection is not working - the network is not visible
to other computers.

Commands used to configure the network in adhoc mode are as follows (wlan0
is the WiFi interface name):

1.	Using iw:
.	ifconfig wlan0 down
.	iw wlan0 set type ibss
.	ifconfig wlan0 up
.	iw wlan0 ibss join ADHOC_TEST 2437

2.	Using iwconfig
.	ifconfig wlan0 down 
.	iwconfig wlan0 mode ad-hoc
.	iwconfig wlan0 channel 6
.	iwconfig wlan0 essid ADHOC_TEST
.	ifconfig wlan0 up



Attached you will find the dmesg messages (dmesg.txt).
Using the latest backport of Compat Wireless backports-3.10-rc1-2 did not
help.
Testing with different WiFI dongles gave different results.
TP Link WN725N that uses the Realtek 8192cu driver and is based on the
RTL8188CUS-GR chipset is working correctly in AD-HOC mode.

Could you guide us in anyway in resolving this issue? 

Pozdrawiam, Best Regards,
