I have a virtual machine snapshot of the kdl so I can use kdl commands in that state.

Is it a GCC4 or GCC2 build? In any case, a disassembly of the frame in question would be helpful ("dis -b 10").

Since there was no "net_buffer" command in your version (I just added it in hrev33893), you could use "dw 0x841fdff8 32" to dump the buffer itself.

I have added a patch that should fix the crash - Axel, could you please review the patch?

The patch was not correct, as it changed the order in which the packets were inserted to the list (Insert(a, b) inserts 'b' before 'a'). Thanks for the quick patch, zooey - I didn't even remember you were the component owner :-)

Fixed in hrev33908.
