I can confirm that I also see this issue on Vultr in a single-CPU ZFS based
system. On checking shutdown(8)
-n If the -o option is specified, prevent the file system cache
from
being flushed by passing -n to halt(8) or reboot(8). This
option
should probably not be used.
So using -n could possibly result in filesystem corruption ?
I also found: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253175
and also possibly related to
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254513 which relates to
virtio_random.
Thanks,
Gautam
