I continued testing with kernels from backports and updated metadata 
accordingly.

Interesting to note is that the 2 kernels that failed, did NOT show any 
message either in my ssh session nor in `dmesg`.

Also interesting is that when it failed, it *always* failed at the first run.

So in conclusion, in *current* Stable and Testing and Unstable the issue is fixed!
