I have worked around this issue(for me) by adding a few lines in debug.sh like:

if test "$1" == "poweroff"; then
 hdparm -Y /dev/sda
 echo o > /proc/sysrq-trigger ; sleep 5
fi

that puts drive to sleep and triggers shutdown via sysrq

Seems to have worked just fine: no drive issues on startup anymore, as I've
mentioned before with having to ctrl+alt+del once to get BIOS to detect drive;
and no extra delays.

Also the above require a kernel patch:
//sd_start_stop_device(sdkp, 0);
commenting out that call in sd_shutdown function in file: drivers/scsi/sd.c
or else it will fail like in comment #3
