Can you tell me if this happens when you boot up outside your dock
station, and then dock/undock, or if it only happens when you boot
inside the dock station and then attempt to undock?

When you do get to this, please load acpiphp as a module with the
debug=1 option and send me the output.  Do the following:

1.  boot outside dock station
2.  load acpiphp
3.  attempt to dock - capture output of dmesg plus lspci -vv
4.  reboot inside dock station
5.  capture lspci -vv

Maybe we can focus on getting docking working right first, and then try
to figure out what's going on with undocking.

Thanks,
Kristen
