Доброго времени суток!
Проблема такая: поставил в ноут SSD Drive Verbatim 47379. От сети всё работает хорошо и шустро, однако при отключении питания начинаются жуткие тормоза. Посмотрел логи, в них следующее:

И так до бесконечности. Включаешь обратно питание - всё нормализуется. Погуглил, нашёл вроде решение проблемы:
max_performance > /sys/class/scsi_host/host0/link_power_management_policy
там при отключении питания оказывается значение min_power. Всё бы хорошо, но данный скрипт приходится выполнять вручную. Нашёл вроде бы настройку в /etc/pm-profiler, но - увы, они не применяются.
Как решить проблему? А то надоело уже ручками скрипт выполнять!
