Comment 24 for bug 199094

I'm affected by this bug. After suspend APM_level is reset to 254

# hdparm -B /dev/sda
/dev/sda:
 APM_level = 254

Settings in /etc/hdparm.conf are ignored

command_line {
        hdparm -S 12 -B 48 /dev/sda
}

Even a workaround with /etc/pm/sleep.d/20_resume

#!/bin/sh
case "${1}" in
 resume|thaw)
  killall ssh
  hdparm -S 12 -B 48 /dev/sda
  ;;
esac

somehow doesn't work. I need to manually run hdparm after every suspend.
