--- Comment #6 from Ariel Millennium Thornton <arielmt@thornton2.com> ---
This may have been a corruption in my pool instead of a bug in zfs.

I found that the only snapshot in my zroot/var/mail dataset that didn't cause a
kernel panic when destroyed was the most recently created.  Destroying every
snapshot in reverse order, from newest to oldest, was successful.  After that,
creating snapshots then destroying the oldest snapshot worked as expected.

I reenabled my zfs-auto-snap cron jobs, and their `zfs destroy -d` actions have
so far all been quietly successful.
