This is what I hoped for ;-) (A bug in the testtooling...)

The system boots and seems to run properly. We did not yet test for a
longer period of time, but the first looks are that the hangups we had
are gone now. But it would be good for the peace of mind if the
locking-selftest was working properly.

Thanks.

Kind Regards,

Remy
