I tried somes NIC (requeired e100, e1000 and tg3), I don't
faces this issue. So, it may be an issue of NIC / driver.

I don't know it's related or not as I don't have Davicom NIC,
it seems that 2.6.15 kernel has an issue with Davicom NIC.
Regarding udev, kernel gets the tulip driver. It seems to cause
some troubles.
