ACPI dump of Thinkpad T42

The USB ports in the Thinkpad Dock or Dock II are only recognised if the laptop is booted whilst docked (you can undock and re-dock and they're still recognised), or if the kernel is booted with acpi_os_name="Microsoft Windows" (which breaks the first dock/undock attempt).

Platform: IBM Thinkpad T42.
Comment 1 Zhang Rui 2010-03-22 08:11:56 UTC 
please attach the dmesg output when
1. boot the system docked, and then undock and re-dock it.
2. boot the system undocked and dock it

BTW: please verify if this is a duplicate of bug #15521.
Comment 2 Paul Martin 2010-03-22 09:17:23 UTC 
This is not a duplicate of bug #15521. The undock button works -- that was fixed for me in bug #15000.
Comment 3 Zhang Rui 2010-03-23 07:39:07 UTC 
please attach the dmesg output mentioned in comment #1.
