Sorry for the late response:
$ sudo sh -ex /etc/init.d/sysfsutils start

+ [ -f /sys/class/scsi_host/host0/link_power_management_policy ]
+ echo -n min_power
Please note that sysfsutils actually set the host0 link to min_power,
however it simply stopped here, whereas the sysfs.conf I set is this:
# this enables lowest power state for SATA link host nr. 0,1,2
class/scsi_host/host0/link_power_management_policy = min_power
class/scsi_host/host1/link_power_management_policy = min_power
class/scsi_host/host2/link_power_management_policy = min_power
# this enables low power state for Realtek HD Audio HDA audio switch
module/snd_hda_intel/parameters/power_save = 15
In fact, manually checking via 'cat' neither host1, host2 nor the
snd_hda_intel module are tweaked accordingly.
