I've had two systems taken down by what seems to be this bug now in the last few weeks. This, together with the mismatched kernel and userspace version of the ZFS tooling is really, really bad.
I do get that a ZFS root and the HWE kernel together is a rather esoteric setup but it's all out-of-the-box available to setup from the installer and repos. At this point any roll out of the 6.5 kernel should not be offered to users with a ZFS root and some sort of official documentation for how to recover should probably be posted somewhere. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/2051999 Title: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.
