I just checked on my Kilauea and reproduced the problem. No, I don't have any clue right now where this problem is generated. I can't remember any issues with PCIe slot 1 on Kilauea.

Linux also does not recognize PCI-E cards. Kilauea board > manual says that PCI > clock is determined by CPLD. Could it be CPLD/FPGA bug ? Is bootstrap option C working? Thanks.
