Ограничение использования процессора и памяти для программ на C, Java на системном уровне

Выход из системы и перезагрузка разрешили обе проблемы. SMART и APM отображаются на дисках GNOME. После повторного включения моего сценария возобновления настройка APM диска будет повторно установлена ​​на 254 после выхода из спящего режима.

Конечно, при перезагрузке было очищено какое-то состояние, которое не было очищено перезапуском udisks.

Это произошло во второй раз, и я заметил приведенные ниже ошибки udev в момент, когда udisks перестали работать.

Запуск sudo udevadm trigger / dev / sda позволил udev повторно сканировать диски и заставил udisks снова работать без перезагрузки. Запуск udevadm info / dev / sda до того, как триггер показал, что отсутствуют атрибуты, которые udisk должен использовать ( diff ).

Время ожидания событий udev истекло, потому что udev считает время, в течение которого они были приостановлены. Я зарегистрировал ошибку с конкретными деталями.

Событие udev запускается во время приостановки для sda, потому что ловушка, которую я добавил для перезапуска udisks, также запускается во время приостановки. Он устанавливает значение APM для устройства, которое требует его открытия (а затем закрытия). События изменения Udev генерируются всякий раз, когда блочное устройство закрывается, поэтому блочное устройство будет повторно сканироваться после запуска такой утилиты, как fdisk или mke2fs.
