Testing saucy iscsi target booted on e500mc default initrd hangs when tg3 driver started.
saucy was installed to an iSCSI target using the interactive setup from:
http://
http://
Linux version 3.11.0-
initrd.
Booted from flash USB to simulate a pxe boot.

with break enabled I can enter cli in the initramfs

(initramfs) ipconfig -t 10 -c dhcp -d eth1 &
(initramfs) IP-Config: eth1 hardware address 02:30:b0:00:10:01 mtu 1500 DHCP
IP-Config: no response after 10 secs - giving up
-> System is alive ( I have a prompt ) - The above SHOULD HAVE WORKED since it is an active port.
