ZEN boot failing on older HW

Hi all: We reuse some old HP VLi8 computers (application
non-cpu intensive). I have always been able to reimage
these old machines via ZENworks 7 (sp1 IR4). However, today
I am seeing the ZEN linux kernel failing to initialize
properly.

During the ZEN boot process I am seeing the following
error:

" : the program '/bin/bash' called '/usr/bin/udevinfo', it
should use 'udevadm info <options>', this will stop working
in a future release "

The ZEN boot process ends at the red window of death: "An
error occurred during the installation".

So I have a few questions:
1. has something changed in the latest ZENworks patches
which have caused my older machines to now fail?

2. could this be hardware (as in failed HDD) related?

Thanks, Chris.
