But I did not have this problem on the previous motherboard, so while the reasoning is good, it seemed to me to have been a software problem. Both boards are running a 32 bit 2.6.27-rc8 kernel. One thing I did find yesterday was that my port forwarded web page access was dead, and in running that down I noted I was on eth1 with the new mobo. It seems something in the network scripts edited /etc/sysconfig/network-scripts/ifcfg-eth1 to enable it and set it for DHCP. I use fixed addressing here at the old farts ranchette, and that address diff meant the Port Forwarding I do in dd-wrt was wrong. So I killed the onboot=yes in eth1, and reset the mac address in ifcfg-eth0 to correspond to the new hardware, did a network restart and that's back to normal, but still with the 5 second lag at bringing it up. Why does the line IPV6INIT=no in ifcfg-eth0 not work? This strikes me as a bugzilla item. Or a just ignore it. :) Now, if I could figure out why grub takes an extra 30 seconds to load and run at bootup. Thanks Ian. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
