dmesg output

Doing a new FreeBSD build with an LSI 9300-8e HBA in IT mode. Firmware on HBA flashed to latest available from Broadcom, 16.00.01.00. The FreeBSD server has 5 JBOD arrays hanging off of the HBA, with a total of 56 drives and what should be a total of 112 paths. With mpr driver version 18.03.00.00-fbsd, approximately 10-15 drives don't show up in camcontrol whatsoever. After upgrading the driver to the latest mpr from Broadcom, version 20.00.00.00, I can now see all 56 drives, but even though the mpr driver shows 112 paths, FreeNAS isn't picking this up and is only displaying 79 total paths. I shot a message over to Stephen McConnell, the original maintainer of the mpr(4) driver for FreeBSD, and he suggested to me that this may be a middleware problem, as the driver itself can see all 112 paths just fine, something must be going on in between the driver and FreeBSD.

I've attached the latest dmesg output as a tar. Happy to provide any other diagnostic information as necessary.
