The SATA drivers have no power-management support (i wonder how this could
happen, since they are brand new, but this is another story...). Jens Axboe
is fixing them up right now, you should be able to find patches for them on
LKML.

This does affect suspend to disk as well as suspend to RAM. Also, since it
seems timing sensitive, it works on some machines sometimes.
