[tproxy] IPTables or EBTables Causing Kernel Panics

Hey guys, We use Slackware 13.0 in bridge mode with no nat or anything with Squid 3.1 and Tproxy using kernel 2.6.31 and during peak loads the box kernel panics with error about the bridge. When the IPtables and EBtables rules are dropped so the box is acting just as a bridge without caching it's stable. Does anyone know what would be causing this? Regards Tristram
