Here are my notes from downgrading from P20 to P19 on a supermicro box.
modify as needed to go from P19 to P18.
downgrade to P19. P20 has serious bugs.
boot into UFI shell
get to usb
get to fw dir
        cd 9211_8i.p19
erase newer fw
        sas2flash.efi -o -e 6
load new fw and bios
        sas2flash.efi -o -l 2118.log -f 2118it.bin -b mptsas2.rom
