Well it's not the .config i'm worried about .. it's the tree it self :)
 .. it was not a pristine upstream tree .. but a concoction of
linuses tree + bluetooth fixes + xen-devel + xen-multi-queue etc.

So i consider it impossible to recreate that at this point.

And unfortunately due to some space limitations, it's build without also 
building
the source .debs

I have now something out of vmlinuz that readelf recognizes but addr2line still 
doesn't give any lines back on any address from that stacktrace :-(
