What firmware is/are on the cards?

In the dmesg output I included:
mpt3sas0: LSISAS3008: FWVersion(10.00.00.00), ChipRevision(0x02), BiosVersion(08.25.00.00)

The driver version difference between C6 and C7 could interact badly with old firmware.

I suspected that was the case, and tried running elrepo's "kmod-mpt3sas" from their testing repo. C7 has version 04.100.00.00, while elrepo's appears to be 13.100.00.00. That didn't change anything.

What firmware does $vendor suggest?

Haven't asked yet, since the same firmware produces different behavior on the two OSs.

I know with the SAS2 chips (SAS2008, SAS2308, etc), FreeBSD strongly recommends the firmware revision matches the driver revision, so if the driver is P20, the firmware also should be P20. I don't have any SAS3 stuff.
