Yup. It seems that your BIOS is being asked to suspend all devices while there is still disk IO being performed. And it refuses to suspend because the disk is still active.
The patch I sent you attempts to put a one-seond delay in the APM suspend function before calling into the BIOS. That _should_ improve your suspend success rate, but there's really not much we can do to prevent disk IO from being started at any time.
