This one:

[    0.197025] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI]                                                                                                                         
[    0.197222] acpi PNP0A08:00: _OSC: platform does not support [PCIeHotplug PME AER]                                                                                                                                
[    0.197408] acpi PNP0A08:00: _OSC: OS now controls [PCIeCapability]               

So native PCIe hotplug is disabled.
