eth1: network connection down



hi

i upgraded my mainboard and cpu today. switched one of my nics from a 10mbit
to the onboard 100mbit.
now i'm having a bad time because i can pppoe fine, but can't ping my
internal lan.

what's the problem? (and how to fix it?)

please keep me in cc:, i'm not on the list.

some output:
