Removed Riser 2, and power cycled the system. Error went away. Reinstalled Riser 2 and error did not return. Seems to be a firmware issue. 
I attempted to move my boss controller from pcie riser 1 to riser 2 and got message of CBL0002 Backplane 0 signal cable disconnected. [IMAGE]   It locks in boot, hit F1 and it allows the boot and all drives work. So how do I resolve this so it quits locking on reboot?
CBL0002 on R7425
