I think it does. after reflashing my last backup was loaded (that i made before i reflashed but after Mer was installed), so it's possible, that it is some wierd user setting that got reinstalled with the backup. And as i said: it worked all very nice before i installed Mer, and i didn't install anything else but Mer. so unless bad weather or full moon aren't counted in, i dont see what else could have done this. i will reflash later without installing the backup and see how that works out, then install the backup and see if i it screws up again. after that i will reflash, install Mer and see what happens. Then we will know, whether it is Mer (or the bootmanager) or not and btw. just saying "no, it cant be the stuff we made, because it worked fine on different model" is not a good way to find possible bugs
