    I was trying to state what you suspected: the condition in the 
assert did not hold so the kernel paniced.

    Will do it tomorrow morning (I'm UTC+1).

    It was an update of a three months old head machine. A dicotomic 
search would be a long process (I'd say).

      I tried 252528 (I picked that randomly, only wanting to try to 
avoid r252695 and r252653 because they state they had to do with pmaps) 
and it works fine. Tomorrow I'm gonna revert to 252653 and 252652 and 
see what happens.

    OFFTOPIC: I used to track src via gitorious but they lag behind and 
the github repo hasn't the svn revisionm does anyone know of any other 
git repo with the svn revision?

   Well, if you need some testing via serial be sure it will be possible.
