Re: ACPI hotplug

Hi Rajesh,

I was hoping that I can use my docking station without
being necessary to boot docked.
But is not the case.
I tried this way:
Booted normaly, loaded acpiphp (even said found a pci
slot), then plug the ThinkPad in the dockingstation,
but nothing happened. No new devices get added.
Then I tried to boot in the dockingstation and while I
see all the new devices (this was always the case), I
cannot remove the laptop from the docking station
because it does not senses I push the eject button on
it.


Thanks,
Paul
