External harddrive not spinning down on suspend

Hi everyone,

I switched from opensuse to Fedora recently and I really like it so far,
I am however having some troubles with my external usb harddrive. On
opensuse the harddrive usually spun down when I sent my notebook into
suspend mode and spun up again as soon as I accessed it after resuming
the notebook. In Fedora the harddrive just keeps spinning when I send
the notebook into suspend and is not accessible after resume. Even
worse, the next suspend fails. Does anyone have any ideas on why or
where to start searching for a solution?

I am using Fedora 14 with all updates installed, the external harddrive
is a Seagate 1,5 TB drive in an icy box with a JMicron Chip, here's the
dmesg-output:
