Good afternoon,

I'm still trying to figure out if I have the latest version of the 
6LowPAN module. I'm currently using the devel branch of the Linux Zigbee 
kernel (rev: 9155ba3a1c13ba, slightly patched the autofs4 files so that 
it compiles) and I did not managed to get the 6LoWPAN part working 
(izchat works great).

It is crashing any of the two testbed computers each time I try to set 
up a 6LoWPAN network (the crash message on the console seems to be 
changing all the time and does not point toward any error in the 802154 
or 6LoWPAN subsystem, but I'll investigate it further if needed). I've 
been using the serial driver (with an econotag) and the fakehard driver, 
both yield the same outcome: the system hangs.

Here is how I reproduce the crash:
> # this line is one with the serial driver
> izattach /dev/ttyUSB1
> iz add wpan-phy0
> ip link set wpan0 address ca:fe:ca:fe:ca:fe:ca:fe
> ifconfig wpan0 up
> izcoordinator -i wpan0 -s 1 -p 777 -c 11 -l lease &
> modprobe 6lowpan
> ip link add link wpan0 name lowpan0 type lowpan
> ip link set lowpan0 address de:ad:be:ef:ca:fe:ca:fe
> ifconfig lowpan0 up

At this point (ifconfig lowpan0 up), the system stops functioning and 
the SSH access is frozen. Perhaps there is a step that I'm missing, I do 
not know. But I start wondering if I am the only one experiencing this 
issue.

Please let me know if you need more information on my system in order 
to help me debug them.
As always, help, in any form, is greatly appreciated.

Regards,
     Tony Cheneau
