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.
