This bug is awaiting verification that the linux-oem-6.1/6.1.0-1009.9
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-jammy' to 'verification-done-jammy'. If the
problem still exists, change the tag 'verification-needed-jammy' to
'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

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.
