(usagi-users 03881) Mobile IPv6 TunnelPayload => kernel panic

Hello,

I am trying to use IPsec to protect payload between HA and MN in Mobile IPv6 environment. I am running the latest 2.6.22.1 kernel with latest USAGI patchs, and linux-2.6-mip6 binaries from USAGI git tree.

Anyway, after the first packet is received by the Mobile Node, it just hangs and panic. I have c/p the panic output at the end of this message.

Any idea why this is happenning?

Thanks,
Sebastien.
