[dapper,edgy,feisty] Thinkpad T60p summarily powers off when docked

Bug Description

When I insert my Thinkpad T60p into an IBM Advanced Mini-Dock, about half the time the power will shut off immediately. No clean shutdown; no user interface interaction. This seems to be most common when the machine was originally booted in an non-docked state or when it's been suspended and resumed while not docked.

IIRC, this stopped happening to me for a while with my dapper installation when I compiled my own 2.6.18 kernel from source without the ubuntu patches. I figured that it was just due to the fact that 2.6.18 introduced real docking station support, but apparently it's still broken in Feisty's 2.6.20 kernel. Also I may be mis-remembering this last part.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We were wondering if you have tested this with the 2.6.22 kernel from Gutsy. Thanks in advance.

I did test it with Gutsy. Although it occurred more rarely, I did have the same effect a few times. It hasn't happened on Hardy so far, but that doesn't mean much.
