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