Title:
cache on NVMe inhibits proper suspend/hibernate - zfs l2arc
Status in zfs-linux package in Ubuntu:
In Progress
Bug description:

https://errors.ubuntu.com/oops/7bb2122e-01b1-11e7-ba2a-fa163e839e11
Running zfs [root] with l2arc cache enabled fails to suspend properly,
screen goes blank but power stays on, when I disable the cache it
works fine. Unsure if this happens with non-root install of zfs, slog
does not cause this problem.
