I have an eSata card in a R710 and tried the same one in a R720 and it recognized it fine, but after the first reboot, where it profiles the card, it comes up with:
fatal pci bus11320
Bus 0 device 3 function 2
And a screen: the system detected an exception during the UEFI pre-boot environment.
Type: non maskable interrupt (02) Source: hardware
and a bunch of address info.
Any ideas to get this card working, or any recommendations on a card that might work.
