Both host A and B runs racoon, configuration snippet is
sainfo anonymous
{
pfs_group 2;
encryption_algorithm blowfish, twofish, 3des;
SPD is simply at A:
spdadd HostB HostA any -P in ipsec
esp/transport//require
ah/transport//require;
spdadd HostA HostB any -P out ipsec
esp/transport//require
ah/transport//require;
B is same manner. When I ping,
connect: Resource temporarily unavailable
after a few second, message is logged that SA is established, then
ping, oops.

Oops occured at crypto_cipher_set_iv() in net/ipv4/esp4.c -
esp_output(). As above, I inserted printk and see ``addr'' at
crypto_init_cipher_ops(). In this time, the kernel is
2.6.13-rc2-git5 but the situation has not changed.
No oops occured on i386 machine so I thought this was specific to
x86_64. If there is another information I can report, please tell
me.
thanks,
