Using rc_debug=yes I see that it is the kernel problem, not rc problem.
Sometimes rc backward sequence executed even fully, sometimes only
partly, but in unpredictable moment inside rc sequence the kernel decide
to reboot quickly (or even deadly hang in rare cases). Always without
any "Syncing buffers..." leaving FS dirty. No zfs etc. just normal UFS,
no EFI, no GPT.
I change GELI swap to normal one, but it does not help. The same
untouched config works for years, I see this bug for the first time in
