Immediately after booting microcore (Downloaded June 24, so it is most likely version 2.11.5) the network interface functions normally. After about 1 minute, ifconfig reports errors on eth0 and I can no longer get a response from any pings.
What could be the cause of this?
EDIT: I forgot to add, this is while booting from a CD. Booting to an old ubuntu install on the hard drive will not generate this problem.
