Sorry for the late reply. My mailbox is missing Ros's reply to me. I inherited a kernel config used here from a previous custom, V1000-based solution. Most likely originally it came from the x86_64_defconfig. Maybe MMCONFIG wasn't enabled by default at that time. We never had problems with this because our BIOS keeps the IO ECS enabled (that's against the spec recommendation). The kernel default for PCI_MMCONFIG is 'y' now, so it's unlikely that people will run into this issue unless they explicitly disable it. Regards, Rostyslav
