Sorry, but I don;t understand, what line, i am not kernel guru. :/

oceanic:/usr/src/linux-2.4.29$ grep  fore200e_send * -r
drivers/atm/fore200e.c:fore200e_send(struct atm_vcc *vcc, struct sk_buff 
*skb)
drivers/atm/fore200e.c: send:         fore200e_send,


Is was happened on 2.4.29, too. It is a interrupt problem?

Below Oops from 2.4.29:
