yes, I tracked it down to the charging code. I think it comes from the 
fact, that layer1 is periodically polled by layer23 (mobile) about the 
current battery-status. And there seems to be a problem with queueing 
these things over the serial line. So if battery-status is polled and 
other things are going through serial at the same time, layer1 crashes 
eventually.

Thats my interpretation, but fact is, if you revert the patch attached to 
the mail, the crashes are gone, but you can't charge. :)

I modified the mobile battery, removing the battery itself, and replacing 
it with a 3.7V AC-Adapter, so that I don't need the charging.

Maybe you can investigate it in more detail? Or better I send it to the 
list too, so the problem could be discussed in the big round again.

Best

Tim
