[Help] N900 boots to black screen
 

Hello,
My baby is in a bad state:
When switching on:
- white Nokia screen
- it boots (in R&D mode, since a very long time) from U-Boot into power kernel 52, as this my default boot setting.
- After it has run the boot messages, it's just the black screen.

The screen remains *lit* though, and the keyboard flickering, indicating system activity - it's just black. It won't turn off after the usual interval for power saving, it just remains lit and black.
There is no reaction to pressing any hardware buttons, except power off.
If I power on with the keyboard open, I get to select the stock kernel or U-Boot console from the U-Boot menu. Booting the stock kernel makes the device *power off* after running the boot messages.
I have CSSU thumb on it, not overclocked, with kp52. U-Boot was for booting other OSes from SDcard.
The last change I made to the system, was to upgrade CSSU to latest Thumb 8.2.
This problem occurred more than a week or so after that, so I wouldn't know what "user-behavior" to link it to. I don't recall doing anything out of the ordinary really.
Suggestions? Possibly avoiding a reflash?
I have Easy Debian installed on an SDcard, maybe U-Boot will allow to boot into that, or maybe I can use the U-Boot console for something. These are just guesses though, I need help for what exactly to try and where...
Thanks, Ben

edit: the screen actually does switch off after a while and lights up again when opening the keyboard

So I just reflashed the fiasco image, and then tried to restore my last backup from sdcard. the backup stopped halfway through though, saying it ran out of memory (1KB of space left, haha). The backup contained pretty much the same state of the system of when the device went black.
I did have CSSU thumb, so maybe that was the reason everything fit in there before.
Does that mean all the apps I had installed were thumb compiled as well?
Anyhow, I guess there'd be a specific order in which I need to restore things, can anybody help me with that?

Re: [Help] N900 boots to black screen
 

after another reflash, without trying to restore a backup, still "not enough space to install new apps" (this time I tried to start with CSSU thumb).
how can it be? memory information in maemo settings says, 23MB left, which does seem awfully little, but enough to install a few more apps...
Maybe I'm gonna turn this story into a blog or sth., so I'll feel more comfortable with nobody paying any attention to it
:-P
