What is the problem? I can press POWER for 2s and it brings me to the power 
menu where i can restart/power off and it works.

Yes it's doing ubifs. JFFS2 maybe had the same problem but i have personally 
never seen it. With ubifs i sometimes get the welcome screen too. It would be 
interesting to explore why the welcome screen shows up. Maybe some config file 
remains open during hard reset and ubifs does not like it.

I think i hit something like this too, but very rarely.

No idea, i get only very few calls so i havent hit it yet.

It would be nice to have application which shows GPS sattelites for debugging 
this. In fact such app is already there [1] but works only with GPSD. I wanted 
to modify qtopia gps api so that it provides GPSD compatible socket so that 
gpsd apps like this one and e.g. tangogps can work out of the box.

You can also try to comment out agps data dumping/restoring in 
/opt/qtmoko/bin/gps* scripts.

I also think 2.6.34 is very usable. If there is problem it's very rare. Andy-
tracking was probably more stable, but also it's ugly mess without future from 
my POV. I can keep 2.6.29 supported forever in my git, but i will probably not 
do any qtmoko releases based on 2.6.29.
