My PXI contoller stopped upon an acquisition error, and then would not reboot until I removed the 6071E card from the chassis. When I put the 6071E back in the chassis the controller again fails to boot.
I agree. It sounds initially as though it is a faulty card. I would try the card in a different slot and if possible, try a different card. If niether of these solves the issue, then I would call in and RMA the card.
