Much! Thanks.

So this looks like the ethernet driver b44 instead of ath5k, I think.

...but this is higher up the stack. skb_gso_segment is about a year old
so it would be odd if there were a bug here. Can you do the following?
objdump -S net/core/dev.o, then find the address for skb_gso_segment,
it should look something like this (your numbers and disassembly will
differ):
00004190 <skb_gso_segment>:
*
* It may return NULL if the skb requires no segmentation. This is
* only possible when GSO is used for verifying header integrity.
*/
struct sk_buff *skb_gso_segment(struct sk_buff *skb, int features)
{
4190: 55 push %ebp
4191: 89 e5 mov %esp,%ebp
4193: 57 push %edi
4194: 56 push %esi
Then find whatever 0x4190 (your offset here) + 0x110 is, and pick about
10 lines before and after that and paste it -- the opcodes in the second
column should match up with the code lines below:
> [ 516.650000] [ 516.650000] [ 516.650000] Code: 3c048007 08010d50

Or you can send me the whole objdump -S output off-list if that's easier.
