EFW 2.2 community crash during PS3 network test

[Guest]

My red network is a cable modem.  Blue is a DLink WAP.  Green is a 24-port 100Mb switch.

After upgrading to EFW 2.2, my Playstation 3 encountered network problems.  It was configured with static IP using ethernet.  I ensured UPNP is disabled on the PS3.  Nonetheless, each time the NAT detection phase of the PS3's network test is performed, my EFW box reboots!  I tried using DHCP on ethernet and DHCP on wireless, but I consistently get the same result.

The EFWs logs show nothing of interest for each crash.  Logs drop off, and the kernel loads a minute later.  Here is the kernel log:
Dec 4 23:43:21 kernel Linux version 2.6.22.19-72.endian15 (root@raphael-desktop) (gcc version 4.1.2 20070626 (Endian 4.1.2-14)) #1 SMP Mon Sep 8 11:49:17 EDT 2008
Dec 4 23:42:23 kernel ipsec1: no IPv6 routers present

Here is the IPSec log:
Dec 4 23:44:29 ipsec_setup doing cleanup anyway...
Dec 4 23:44:29 ipsec_setup stop ordered, but IPsec appear to be stopped already!
Dec 4 23:44:29 ipsec_setup Stopping Openswan IPsec...
Dec 4 23:44:28 ipsec_setup ...Openswan IPsec stopped
Dec 4 23:42:18 pluto[3766] loading secrets from "/etc/ipsec/ipsec.secrets"

I was hoping to at least find a kernel panic or something to work with, but I have nothing.  Any assistance would be greatly appreciated.
