Subject: How to cleanly detach port multiplier ( pmp )

I can write to the delete file in the sysfs node for the scsi disk to
cleanly stop the disk and detach the scsi disk driver, but I can find
no similar way to delete the ata link, the pmp, the master link to the
pmp, and disable the ata port. How are you supposed to disconnect a
port multiplier without causing the kernel to go into error recovery
because the link went dead and the device vanished?
