After upgrading to 11.2.2 from 11.2.1 MU1 we can no longer network image Dell Latitude 2100 2110 and 2120 netbooks. The boot process stops with a red dialog box that says "Could not find the zenworks repository". It looks like it is correctly identifying the network adapter as a Broadcom BCM57760 and is loading the tg3 module however if I run ifconfig I only see the loopback and ifconfig eth0 reports device not found.

Looking in /var/log/boot.msg I see

tg3 mdio bus: probed
tg3 0000:09:00.0: No PHY devices
tg3 0000:09:00.0: Problem fetching invariants of chip,aborting

Any ideas before submitting an SR?
