Got this lockup when editing a 64M file with emacs - about 122M
resident at time of crash, and about 10M swap used.

Kernel panic: skpush:under: 001404c0:1918

001404c0 is linux-2.0.31/net/ipv4/ip_output:ip_send_room+132

ie. from line 242

memcpy(skb_push(skb,dev->hard_header_len),rt->rt_hh->hh_data,dev->hard_header_len);

This is a pentium-200 with 128M ram
