We had the known boot loop issue (TID10100142), so I applied the ZDM65SP2
Hot Patch which is not in full release yet.

What a disaster! Imaging then had a big hissy fit and I started getting
errors. Namely, Load.dnx error downloading "D"!

I tried to be smart and replace the TFTP folder with a standed SP2
version but started to get other errors.

To fix imaging not working at all I re-applied SP2, but the boot loop
issue is still presenting itself.

Suppose I better wait for the final Service Pack.
