Hi Joseph, The iomem looks very interesting cause it shows that your BIOS works absolutely correct and even resizes the BAR of the devices. Unfortunately that is not a full dmesg from the boot you attached, but just some random audit messages. If you are on a systemd based system please provide the output of "journalctl -b" as well. And to answer your question the DRM subsystem in the kernel allows for a maximum of 128 devices IIRC. But before you reach that you certainly run out of address space for VRAM. Would still be interesting to see if that works with more than 9 cards. Regards, Christian.
