You seem to have a machine where you can trigger the "Resources present before probing" message. Would you mind enabling CONFIG_DEBUG_DEVRES=y and adding "log_devres=1" to the kernel command line so that we can understand what kind of resource is attached to the AMD IOMMU, and where that happens. I don't see invocations of devm_*() in arch/x86/ or drivers/iommu/amd/ that would explain the error message. Just so that we get a full understanding of the issue, independently of the AGP driver probing everything. Thanks! Lukas
