I still encounter this error running Arch with Grub version 2:2.12rc1-5.

I Had to destroy the pool and recreate one, then disable snapshotting on the "boot" pool as a temporary workaround.

Were these patches ever incorporated? I install using Gentoo, the 9999 build and I believe it pulls in whatever is current in git. The bug is still present.

I have posted couple of zfs patches to mailing list recently. They look similar. Can you test them?

Once a zfs-based boot pool is snapshotted, it renders it unreadable by grub. Even removing the snapshot doesn't help.
