I finally managed to get my N900 stuck on a reboot loop while trying to install the latest kernel power boot image (so it can work with multiboot).

The latest kernel power has rendered the original nokia kernel useless (the entry does not work) so I am unable to boot back up.

Thankfully, I had Backupmenu installed.

I've managed to get USB Networking working, ping it successfully, start up an ssh server and even start up the usb console but I am stuck. What are the credentials in order to SSH into my n900? What is the default password? I've searched for about an hour and have not been able to find conclusive results. I know what I need to fix and what files to scp into my n900 but I am unable to get access to it.

Edit: Nevermind, I ended up fixing the problem.
