https://bugzilla.kernel.org/show_bug.cgi?id=42809

           Summary: kernel panic when receiving an ipsec packet
           Product: Networking
           Version: 2.5
    Kernel Version: 2.6.32.54
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: IPV4
        AssignedTo: shemminger@...ux-foundation.org
        ReportedBy: darkbasic@...uxsystems.it
        Regression: No


As soon as I receive an ipsec packet (NETKEY of course) I get a kernel panic.
Even magicsysrq keys do not work anymore.

O.S. Debian Squeeze amd64. I tried both Strongswan and Openswan.
