We had a problem trying to restore an image on an HP D530. The symptom
was that it would always lock whn it tried to restore the files. It
happened in the beginning of the process.
What we found to be the culprit was a firewire card. We pulled the
firewire card and everything restored beutifully. I could not find any
info out here on this so if you are experiencing this, try the card.
