Hi Yinghai,
I went to re-test the acpiphp and pcie_aspm=off to be sure I really have to use pciehp.

Here I just want to show that pcie_aspm=off is really interpreted and that acpiphp brings
me nothing?

In other words, when I use pcie_aspm=off and have CONFIG_HOTPLUG_PCI_ACPI=y my acpiphp picks up
but express card does not "work"?

The only way to have it working for me is to avoid pcie_aspm=off altogether and not bother about
CONFIG_HOTPLUG_PCI_ACPI value. What do you recommend me?

Just to make sure there is no way to use acpiphp on my system. Or could the "Unable to request _OSC control"
thing be fixed somehow?

Thanks,
