I've got exactly the same problem on a machine, running 7.0-BETA1. The
Problem occurs during the boot, when dhclient is trying to get IP. The
messages are occuring all the time an it's not possible to use the
network card at all.
In my case, the network card and the soundcard are sharing an irq. If I
don't load the the snd_emu10k1 driver, the network card works perfectly.

The problem doesn't occur with 6.2
