That info is from: zpool status -v I've worked around this suspend issue by writing a script to take the NVMe L2ARC cache offline during suspend, and bring it back online on resume.
The issue with bcache on suspend that I had for a similar situation is because a read can trigger a write to the cache when writes have been shut off during suspend. Potentially, ZFS could temporarily disable writes to the L2ARC during suspend and reenable on resume to prevent writing when unable to. -- 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/1670137 Title: cache on NVMe inhibits proper suspend/hibernate - zfs l2arc Status in zfs-linux package in Ubuntu: In Progress Bug description: Please see: 2017-03-05 09:03 2017-03-05 14:03 UTC KernelOops linux-image-4.4.0-31-generic 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.
