Since it is a still issue on mainline and next,
Bisected and reverted patch ^ causing kernel warnings at boot time
but finding the SSD drive,
[bcb81ac6ae3c2ef95b44e7b54c3c9522364a245c]
iommu: Get DT/ACPI parsing into the proper probe path
pcieport 0000:00:00.0: late IOMMU probe at driver bind, something fishy here!
WARNING: at drivers/iommu/iommu.c:559 __iommu_probe_device
I see boot warnings [1]
I am happy to test debug patches if you have any.
