ccb request error

[Propaganda]

Running TrueNAS 12.0U2.1 as well as FreeNAS 11.3u5. Booting off ssd attached to my motherboard sata controller. Supermicro X9 motherboard, 96GB RAM, e5-2667v2, TQ backplane (direct attach), lsi 9300-8i (cross flashed m1215), HGST HUSMM1640ASS205 drive. Let me know if you need any other pieces of system setup information.

Very simple setup with just a single drive vdev, for testing. Tried 2 different identical controllers, both have the same issue. Tried 2 identical drives, both show the same issue. Tried 2 different ports on backplane, both show the same issue. Swapping to an intel s3710 drive seems to make the issue go away. Before I cross flashed to the lsi firmware it also appeared like this problem wasn't happening. Anyone have any ideas?
