I see many many `unaligned accesses' when the IP header is accessed (ip_input.c:410 and 423) It looks as if the IP header is two byte aligned, when it ought to be 4-byte aligned. The error message is, e.g., kernel unaligned access to 0xe000000128d8881e, ip=0xe0000000047ba2d1 0xe0000000047ba2d1 is ip_input:410 if (iph->ihl < 5 || iph->version != 4) goto inhdr_error; 0xe000000128d8881e is what's calculated as &iph->ihl The obvious approach of realigning the SKB by 2 bytes seems not to work. Any ideas? -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc@gelato.unsw.edu.au You are lost in a maze of BitKeeper repositories, all slightly different.
