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? -- You are receiving this mail because: You are watching the assignee of the bug.
