Comment 20 for bug 18864

In Intrepid my ThinkPad X61 would freeze when I tried to remove it from the UltraBase X6 without deleting the Ultrabay Slim drive device first (using "echo 1 > /sys/class/scsi_device/1:0:0:0/device/delete"). The prepare-for-undock button on the UltraBase had no useful effect.

In Karmic:
* The X61 never freezes, even if removed from the UltraBase without any preparation.
* The prepare-for-undock button on the UltraBase X6 causes UltraBase devices, including the Ultrabay Slim drive, to be deleted.
* If the prepare-for-undock button is not pressed before the X61 is removed from the UltraBase then USB devices connected to the UltraBase do not work after redock.

Re: #404655 which asks for Fn-F9 to cause preparation for undock just like the prepare-for-undock button: In Karmic, pressing Fn-F9 has no effect on my ThinkPad X61. How might one map the Fn-F9 keypress event to a prepare-for-undock-button event?
