I am also seeing this issue with zfs and l2arc cache on an NVMe and 4.10.14 on zesty. I've seen it in the past with btrfs, and a bcache cache on NVMe as well, but not with the bcache cache on a SATA SSD. I will move my zfs l2arc cache to a SATA SSD to see if that fixes suspend. This is probably an issue in the NVMe kernel stack.
