Nothing that stands out for me, but then I'm not into FreeBSD kernels.
But there is certainly no more userspace processes running other than
reboot.....

Certainly no postfix, that could complain about missing libpcre.so.1
That seems to be something that should have been flushed from the
print_buffer before.

What I do see i a huge amount of ZFS threads....

Rebooting from DDB is instantaneously...

So I'm not certain what to look for further?
