I'm seeing some LORs on a fresh install of 11.0-ALPHA5 - single-disk =
zfs, unencrypted.
There's some similarity to kern/209816, but mine are on unmount.

It seems to happen on shutdown. I don't think I've seen it hang.
The log shows one involving ufs instead of zfs, unfortunately without a =
stack.
I'm not sure why that is, unless it was the installation memstick.
There's another, probably unrelated, LOR that I'll put in a second =
message.
Thanks,
