Reverting the commit helps but it has another drawback, which I originally tried to solve with the commit, that the PCIe hierarchy wakes up immediately after being put into D3cold. This series of two patches tries to fix both issues so that PME wakes up from D3hot and that the hierarchy does not wake up immediately from D3cold.
