Public bug reported: Everything worked fine in Hardy (2.6.24-21), bay device appeared under /sys/devices/platform/bay.0. After upgrading to Intrepid (2.6.27-9) both ACPI and thinkpad_acpi (/proc/acpi/ibm/bay) fail to install bay device handler, so it is not possible to correctly power off UltraBay for hot swapping.
