The failure,
klog: HIGH Kernel message: [ 0.481244] \_SB_.PCI0:_OSC invalid UUID
seems that the NEXP equal to 0, that cause firmware report invalid UUID, need
firmware to check.
If (LAnd (LEqual (Arg0, GUID), NEXP))

Else

Or (CDW1, 0x04, CDW1)
Return (Local0)
}
This _OSC optional object is a control method that is used by OSPM to
communicate to the platform the feature support or capabilities provided
by a device’s driver. This object is a child object of a device and may
also exist in the \_SB scope, where it can be used to convey platform
wide OSPM capabilities. When supported, _OSC is invoked by OSPM
immediately after placing the device in the D0 power state. Device
specific objects are evaluated after _OSC invocation. This allows the
values returned from other objects to be predicated on the OSPM feature
support / capability information conveyed by _OSC. OSPM may evaluate
_OSC multiple times to indicate changes in OSPM capability to the device
but this may be precluded by specific device requirements.
In summary, failing to evaluate _OSC may cause some features to be
disabled. For instance, some advanced PCIe features such as ASPM or PCIE
hotplug will be disabled.
