Hi Alex, I think there is a missing kfree_skb in lowpan_frag_recv, Here's a patch, can you verify if this is the case.
Sadly I'm still seeing lock ups but as your setup is ok I'll explore other avenues with my setup. One thing I have noticed is that the lock ups are different now in that before some pings would get through every now and again and if I stopped the ping and restarted with a small payload size they would work. Now it locks up for good which really does make me suspect my driver, or maybe I'm missing some important Xilinx kernel patches. Cheers, Martin.
