Got it working! Ian's suggestion worked.... i had to make clean, make mrproper, and completely build from scratch Bahhh 2.4 Thanks for your help Randy also, and all others who responded - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
