tearing my hair out here. I've got both a 5700xt and a 7900xtx that wont show up. I've tried every slot it will fit in, and also the others with a pcie riser card and none of them get either card to show up in lspci. I've plugged and unplugged all the power cables dozens of times. I've tried different pcie riser cards, including a short stubby pcb one that should be pretty reliable as there is no cable involved in that one. by default all the pcie slots are set to auto link size and speed, but I've also tried forcing 16x and gen 3, but nothing helps. both cards not only work in my threadripper machine, but they even both work at the same time.
I have first graphics device set to external, I have two monitors plugged in, the power cables and psu work with the cards in my other machine. I have iommu on and srv-io on if that matters.
Any ideas guys?
