Subject: 2.6.25-rc2 Thinkpad T30 docking fails with oops.

Now, this was working in 2.6.23, but is not in any later kernel. Previously
reported, but I guess that the previous report was ignored due to the kernel
being tainted. Well, there's nothing other than pure Linus here.

When booted up docked, there is no oops until you try to undock.

Whilst I will be looking for replies in the list, I'd appreciate being CC'd
on any replies.
