I can make this lifimage available ... I will you a url once I have this
setup.

Ah .. I was under the impression it was a boot problem.  I will perform
the find, fsck and tar tests tests ... I only have a small disk (~500MB)
in the system so i will probably need to setup some external disks.  I
will try the tests w/o using software raid first, then add in the
software raid as a an additional variable.  This may take me a couple of
days to get this accomplished (busy work schedule :().

Thanks!
