You had a handful = of extras in there to print things things from the IORT. Also seeing that N= VMe hangs in nvme_ctrlr_start_config_hook, maybe we want to add some verbos= ity to sys/dev/nvme/nvme_ctrlr.c to see what it's waiting for? Also worth sharing, it looks like NXP's reference board also puts the root = complexes behind the SMMU, so that's coming from further upstream, not SR. https://source.codeaurora.org/external/qoriq/qoriq-components/edk2-platform= s/tree/Platform/NXP/LX2160aRdbPkg/AcpiTables/Iort.aslc?h=3DLX2160_UEFI_ACPI= _EAR3
