I do not see such a message.

Now that you mention the bay driver... the funny thing is that
there *is* a /proc/acpi/ibm/bay file.  With the X61 docked in its
UltraBase X6 whose Ultrabay Slim contains a DVD drive, the
file has this content:

# cat /proc/acpi/ibm/bay
status:        occupied
commands:    eject

Experiment reveals that if I do "echo eject > /proc/acpi/ibm/bay"
then I get the same result as I get if I press the "undock" button
on the side of the UltraBase -- namely a hard lockup.

(The hard lockup can be avoided by doing

echo 1 >  /sys/class/scsi_device/1:0:0:0/device/delete

first.)
