\_SB.PCI0.PEG0.PG00 by calling its _OFF method (happens when the root
port is runtime suspended). This ends up calling \_SB.PCI0.PGON which
calls \_SB.PCI0.PEG0.PEGP.NVPO.
The last method looks like this:
Method (NVPO, 0, NotSerialized)
{
While ((\_SB.PCI0.P0LS < 0x03))
{
Sleep (One)
}
So basically it polls P0LS register infinitely if the returned value is
less than 3. I suspect this is the issue and it then makes the other
like wifi to fail to execute its methods.
P0LS comes from this operation region:...
