freebsd stable - Nov 2019 - Cisco 12G SAS RAID support (FreeBSD 12.1-RELEASE) ?

Chris,
After you've booted the kernel, the correct way to load a module that
isn't
already in the kernel, is to:
kldload mpr
To check if mpr is loaded, try
kldstat -v|grep mpr

However, if you've already placed
mpr_load="YES" in your /etc/loader.conf and rebooted your device, then
you
probably need to move into a diagnostic phase.

Thanks for this.  I was able to boot and verify that pci/mpr is already
loaded, and trying "kldload mpr" reports that it's already loaded
from the
kernel.  So, device just not recognized.

Yeah.  I think I see what PCI id is missing in the driver, after digging
around in the sources.  I was just hoping it was a process/human error.
I'll get another machine running a build, and see if I can stub it in.

Thanks all.
