Bug Description
[Impact]
When TBT dock is plugged, system wakes up immediately after shutdown.
[Fix]
"ACPICA: Events: Support fixed PCIe wake event" to properly support fixed PCIe wake event.
Opposite to other ACPI events, the PCIe wake event gets enabled during boot up and gets disabled on S states like S5 shutdown.
[Test]
The spurious wake up is no longer observed when
[Where problems could occur]
I did some quick tests and didn't see any negative impact.
However, since ACPI fixed PCIe event now is enabled when system is running, events like runtime PCIe D3cold wake can be affected.
