SATA.  Currently Intel SSDSC2BB24 but like I said, we've tried several.

HBA is a Supermicro AOC-S3008L-L8I (reports itself as a LSI3008-IT).

Firmware has been updated to latest on all controllers.

We've purchased an LSI 9300-8i and scheduled downtime to install it, to
see if we can rule out a bad controller.

No, the pool is on separate HBAs.  Only the cache and log devices are
attached to this HBA.

8 11-disk raidz3s.  We've tried various numbers and configurations of
log devices, anywhere from 4 to 8 devices, both mirrored and unmirrored.
