--- Comment #21 from Mika Westerberg (mika.westerberg@linux.intel.com) ---
Thanks for the logs. For some reason the two downstream PCIe ports (2d:00.0 and
2d:01.0) that lead to the xHCI and the NIC get their bridge windows reset to 0
and this prevents drivers from accessing their MMIO registers. I also see that
you are not running the mainline kernel so can you take v5.8 vanilla kernel and
try that and add "pcie_port_pm=off" to the kernel command line to disable
runtime PM of those ports.
