yep, this boots fine. The toolchain problem is weird. Maybe we should compare 
the disassembly between 4.6.1 (I have gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 
4.6.1) and 4.6.2 (where to get this from)? Are you using a cross compiler or 
native? 

Jani, it also seems you forgot to sound support. You need to enable some 
codecs, I know it works on 3.0 if it is enabled ...

ah, native. So I'll need to upgrade tho 12.04 I guess to be able to reproduce 
it :-(

Thanks
