Hi all,

I'm still trying to use 6LowPan on my serial device.
But it does not work. I did successfully recompile my kernel and modules for my 
Linux 64 bits architecture, ubuntu 11 ...
But maybe "Linux-Zigbee" things can't work with this architecture?

All seems verify fine except that when I set my lowpan interface UP, it gets UP 
but the following kernel messages occur (See last paragraph).

Please hints ?

Here is my kernel version:
--------------------------
Linux watteco-X610 3.0.0-rc4+ #1 SMP Mon Dec 19 14:31:58 CET 2011 x86_64 x86_64

Here are my loaded modules:
