Once a week or so there is a system running 5.3-STABLE that panics for
unknown reasons (at least to me). I haven't managed to reproduce the
problem at will but I did manage to get a dump and do a backtrace.
The kgdb session goes likes this:

--------------------8<--------------------8<--------------------
A couple of considerations insipired by a blunt keyword matching of
the forementioned logs:
- as far as I know I don't run any process in jail. Jls in fact
doesn't report anything
- if I remember well the day when I prepared this system, the only
bleeding-edge technology it's using is gmirror.
Is there any way I could gather more clues about this problem?
Thanks in advance.
