Public bug reported:

Binary package hint: pm-utils

When the script /usr/lib/pm-utils/power.d/hardrive is run and the system
contains an SSD not a HDD and error can occur.

On SSD systems we should not be passing -M to hdparm as the acoustic
management setting is not valid.

On my SSD calling hdparm with -M causes the ATA drive to reset with the
following error in kern.log

kernel: [   19.010138] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action
