Yes, right.

Hmm.. as long as the event is only delivered when the device is actually
connected behind dock, I think it's okay.

Does the attached patch fix the previous undock problem?  It now
explicitly tells libata EH to detach the notified devices on
EJECT_REQUEST and wait for EH to complete such that control is returned
to ACPI after all notified devices are actually detached.

Thanks.
