Thanks duanedesign. This is still a problem for me with my Sony VGN-
SZ3XWP in Sony docking station.
Jaunty 9.04, up to date as of today:

Where I refer to "undock script" below I mean this two-liner adapted from
Chris' original bug report:
sudo modprobe acpiphp
sudo echo 0 > /sys/bus/pci/slot/4/power
Behaviour
1. Removing power from docking station, or pulling out laptop without
undock preparation
Hard hang of laptop with flashing status lights requiring battery
removal.
2. Pressing undock button on docking station, then removing laptop.
Hard hang of laptop with flashing status lights requiring battery
removal.
3. Don't press undock button, run undock script, then removing laptop.
Wired networks disabled. Laptop undocks. When re-docked, running "sudo
echo 1 > /sys/bus/pci/slot/4/power" seems to reenable wired network 50%
of the time.
What happens if you press the undock button on the laptop?
The dock light will go off (yay!) and wireless will be immediately
disabled (boo! why would I want to turn off wireless when undocking?).
Wireless will not reenable when docked (ack, reboot required?). Nothing
else seems to get turned off... and it doesn't alter affect scenarios 1
- 3.
The only way to undock the laptop is with the script I provided above,
and re-docking is unreliable.
