I will just comment the LDDSTM out for the moment.
Another thing, I wanted to dump the received sk_buff raw data using the following sequence but get kernel panic. The question is, is it safe to free the new_skb in the following manner.
new_skb=skb_copy(old_skb, GFP_ATOMIC);
....
kfree_skb(new_skb);
Or if there are other prefered way to get the raw data(including ethernet header) from a sk_buff?
Thanks,
David

Its just a debug message. Just comment it out.

Actually, it's the line
b64: e8930003 ldmia r3, {r0, r1}
You can verify this in the error message:
LDMSTM: PC = c0121ed4, instr = e8930003 [...]
----------------
(Remember that the PC always shows two instructions ahead of the instruction
currently being executed.)
Now the problem here seems to be that r3 isn't word-aligned:
r3 : c31f4032
