cdcontrol close: Invalid argument

[Alex Goncharov]

On one of my FreeBSD 9 machines, 'cdcontrol eject' works fine but
'cdcontrol close' fails.  Any ideas on the cause? (I have never seen
anything like this on other machines, in any FreeBSD release.)

Starting from the closed tray and seeing a successful physical eject:

----------------------------------------
dmesg > /tmp/d1; id -u; uname -r; for c in close eject close; do
cmd="cdcontrol $c"; echo == $cmd; $cmd && echo 'OK' || echo 'not OK';
done; dmesg > /tmp/d2; diff /tmp/d1 /tmp/d2

== cdcontrol close
cdcontrol: Invalid argument
not OK
== cdcontrol eject
OK
== cdcontrol close

not OK
