Trying to get the pciehp module to work on the above system. I can see it register but then nothing happens. I suspect there is something missing that I don't see ATM. Any clues what to look for? Jocke

I do not think P2010 has a functional pciehp module in the pcie controller. Roy

Maybe there is, see my latest mail to the list (today) titled: mpc8xxx PCIe hotplug needs fixing, some clues

No. if you check the hotplug register in configuration space in P2010, which missrd some important bit define for hotplug, for example, "Data Link Layer State Changed" in slot status register. And more, hotplug needs extra hardware pin in the silicon, which is missing= for P2010. Roy

Too bad, but one might be able to use something else, just guessing though. However, performing a manual rescan should do the trick. Perhaps you could comment on the "mpc8xxx PCIe hotplug needs fixing, some clues" mail too?
And more, hotplug needs extra hardware pin in the silicon, which is missing for P2010.
Ohh, what is the name of this pin? Jocke
