You can't break it, they said. Try, they said.

Hmm... OK, assuming you can get to a mode where port 22 works, log in via ssh (e.g., putty on WinDoze) as "admin" with no password. Once you're in, issue the command "dmesg" and capture the output. Then paste that into CD so we can take a look at the output of the boot cycle.

Additionally, do you have the serial port hooked up by any chance? If the serial console is enabled, you should be able to capture the boot sequence via Hyperterm, putty or some similar terminal emulator. That info would be most useful in determining what's going on during the Linux boot cycle. At least with that, we should also be able to see the boot loader code running.
