Honored ContributorI am really surprised that it is still not working, maybe Terasic's diagnose script is broken? Have you tried an actual OpenCL kernel to see if it works? You can try Altera's hello_world example.
Regarding the board disappearing from lspci: if you do a full shutdown and start up, the FPGA image will be wiped due to power loss but if you have put the image on the on-board flash, the board will be reprogrammed again after start up. If your machine fully boots before the FPGA is fully programmed, chances are the OS will not recognize the device and ignores it and that is why you don't see it in lspci, but after a soft reboot, the device shows up since it is already programmed. I find it quite unlikely for the FPGA to take so long to be reprogrammed. I recommend contacting Terasic, maybe the board is really faulty.
