--- Comment #13 from Mika Westerberg (mika.westerberg@linux.intel.com) ---
IO space is not necessary with PCIe devices so that should be fine and
expected.
However, MMIO resources below the dock PCIe switch upstream port look weird and
I can't see in the logs any failures.
One thing I can suggest to try is to enable IOMMU since ICL kind of expects it
to be enabled so in theory if the BIOS leaves the IOMMU configured or so it
could manifest like this. Can you set CONFIG_INTEL_IOMMU=y in your .config and
try again?
