The box in question has been setup 6 weeks ago with FreeBSD 13-CURRENT natively. It is now a
wreck. Other systems running CURRENT (as of the most recent revision as of today) were
partially installed as 12-STABLE/12-CURRENT and "moved on" to what is now 13-CURRENT. They do
not(!) indicate such problems reported.

Either I hit the crap installing a new system whilst there was a problem, or something really
strange happened. 

The bad thing is that kernel.old exits/dies with an exception and /boot/kernel/ seems to be
completely corrupted. Tomorrow I try to install a prepared pkg tar arcive FreeBSD-kernel from
aCURRENT pkg base and hope this will fix the issue.

Regards,
