Кто-то тут изумлялся, почему у него не подымается IP? ;) А не более ли чем одна у Вас карта?
Повесте кто нибудь за меня это на bug interface - у меня http уж больно сильно зарезан..

[root на ws002 root]# /sbin/dhcpcd eth0

[root на ws002 root]# /sbin/dhcpcd eth1
[root на ws002 root]# echo $?

[root на ws002 root]# /etc/rc.d/init.d/network stop

В /etc/sysconfig/network-scripts/if-up в этом кусочке
if [ -n "$DYNCONFIG" ]; then
echo -n "Determining IP information for $DEVICE via ${DHCP_CLIENT##*/}..."
if $DHCP_CLIENT $DHCP_ARGS; then
echo " done."
else
echo " failed."
exit 1
fi
конфликт с возвратом $? от dhcpcd <interface>.

Таким образом баг в самом dhcpcd который не отрабатывает корректно ситуацию с двумя картами.
