The one liner works here, I can no more solidly hang
the machine. There is still a bunch of error messages
on drive removal though:

mediabay0: switching to 7
mediabay0: powering down
media bay 0 is empty

mediabay0: end of power down

On insertion there are also a few messages
but they seem normal:

mediabay0: switching to 3
mediabay0: powering up
mediabay0: enabling (kind:3)
mediabay0: waiting reset (kind:3)
mediabay0: waiting IDE reset (kind:3)
mediabay0: waiting IDE ready (kind:3)
