This reinitializes the controller, which is probably why things work
better for you (which does of course touch hardware...).


the pitfall for forcing pciehp when the BIOS hasn't provided OSC is that
you don't know for sure that you really have gained control of hot plug
operation properly.  You can obviously try it, using the provide forcing
option as you have done, but the behavior is not predictable.
