Trying to add this controller to my system but getting errors in the system log. unRAID seems to be loading the driver for the controller but doesn't seem to be able to access the drives. What's going on?

After 2 weeks I was finally able to mess around with this again. Disabling VT-d in the BIOS fixed this. Thank you for the info.
