Don't know if I got the exact same issue, but last night I was using N900 with CSSU-Testing and was working fine..

Have also installed EasyDebian and Ubuntu and Fedora images per another post....have 32GB microSD card in card slot....

Don't remember exactly, but think my N900 may have crashed....rebooted and got into backupmenu program. Hit q to reboot and no go...since then can't start up N900....

Thinking it might be battery that got low, I plugged it into AC charger all night long. When I got up this morning I didn't see the green light, no light on. I unplugged charger cord and tried to boot, but nothing happens. Took out battery and then reinserted it and still can't boot...

Plugged AC cord back in and I am getting flashing orange (think it's orange...) light....

Do i need to reflash or ?

Thanks!
