e1000e is turning on and off my network card repeatedly

[borfig]

I have:

00:19.0 Ethernet controller: Intel Corporation 82566DM Gigabit Network Connection (rev 02)
and it works perfectly with my current 2.6.37 kernel on the old Linux distribution I want to replace.
But when the Ubuntu 10.10 installation CD boots, it behaves very strange. here is the kernel log grep'ed e1000e, after I did a rmmod and modprobe, and tried to configure static IP:

Same thing happens with dhcp.
I won't have Internet access after install Ubuntu 10.10 and that's a shame :(
How do I fix this?
