Hi,

I'm running an ad-hoc network with two pandaboards using the following commands to setup the network:

root@panda0 # ip link set dev wlan0 address 7e:78:47:8c:26:52
root@panda0 # iw dev wlan0 set type ibss
root@panda0 # ip link set dev wlan0 up
root@panda0 # iw dev wlan0 ibss join panda-mesh 2412 02:72:CF:28:19:1A
root@panda0 # iw phy phy0 set rts 100
root@panda0 # ip addr add 10.10.10.52/24 dev wlan0

and

root@panda1 # ip link set dev wlan0 address 7e:78:47:8c:26:53
root@panda1 # iw dev wlan0 set type ibss
root@panda1 # ip link set dev wlan0 up
root@panda1 # iw dev wlan0 ibss join panda-mesh 2412 02:72:CF:28:19:1A
root@panda1 # iw phy phy0 set rts 100
root@panda1 # ip addr add 10.10.10.53/24 dev wlan0

After this, the nodes list each other in a station dump. I then run ping:

root@panda0 # ping 10.10.10.53

but only two requests are transmitted before the devices restart as seen in the attached dmesg logs. The tcpdump from panda1 is attached in tcpdump.txt. I have attached the kernel config and here is some additional info:

root@panda0 # uname -a
Linux n52 3.1.6-1-ARCH #1 SMP PREEMPT Tue Jan 3 03:26:01 UTC 2012 armv7l ARMv7 Processor rev 2 (v7l) OMAP4 Panda board GNU/Linux

I see some commit logs from medio 2011 about the wl12xx watchdog, so I assume that they have made it into the 3.1 kernel.

Kind regards,
