Виснет Gentoo на ноуте iRu 1214

Похоже что проблемы все таки в железе:
1. Для начала почекить память (memtest).
2. Бук старый, проблема может быть еще в перегретом проце.
3. Если предыдущие пункты все ОК - тогда проверить жесткий диск.
4. Если и тут все ОК - проверить видюху.

Но мне кажется у тебя чего-то с процом и/или с мамкой - поскольку тест памяти не проходит.

Если время примерно одинаковое - похоже на температуру. Может профилактику пора сделать?
Температуру винта с большой вероятностью можно посмотреть:
# smartctl -A /dev/hda | grep Temperature
smartctl входит в smartmontools
Остальные датчики нужно крутить lm_sensors
Что в логах?

Огромное спасибо за ответы.

На температуру похоже мало, пару раз было, что бук подвисал при самом включении на первом же emerge ... Опять же если выключить/включить после повиса, то бук продолжает работать.
Посмотрел на камень, вытер, намазал новой пастой.
И до кучи нашел некий джампер, который в 3 положениях переключается: 1.3V, 1.5V, 1.525V. Поставил на 1.3 - виснет почти сразу, 1.525 - пока работает (стоял на 1.5), но memtest по прежнему не проходит, просто выключается на каком-то проценте.
Возможно, что и железка виновата, но, что странно, винда на буке работает отлично.

А выдрать планку памяти 256Мб пробовали?
Сисовский чипсет не лучший в случае работы с планками разного объема.

"Local APIC support on uniprocessors -ДА (Желательно)
Если у Вас в процессоре есть контроллер прерываний. Если же его нет, то ничего плохого от включения не произойдет. Однако на опыте я столкнулся с тем, что если на некоторых материнских платах APIC реализован с ошибками, то это может привести к периодическому зависанию компьютера и неработоспособности некоторого встроенного оборудования. Если у Вас возникнут такие проблемы, то пересоберите ядро с отключенным APIC"

Все ухищрения с камнем ни к чему не привели.
Температура не влияет точно, поставил периодическую запись в в файл через cron, перед зависом абсолютно разные значения от 48 до 79 С, с жетским тоже самое 52-54 С.
Одну зависимость точную вывел - вешается на emerge и на make ядра, не всегда, но именно на них.
Дособираю все это дело и отдам на экстримальный тест - мамины пасьянсы в течении 8-10 часов :) Не выдержит - залью винду и отдам сыну на поругание.

для тестов:

"OCCT Perestroïka 1.1.0" http://overclockers.ru/download?961:OCCTPT1.1.0.rar
Красочный тест стабильности для проверки памяти и процессора на предмет отсутствия ошибок при разгоне.

"S&M 1.9.0a" http://overclockers.ru/download?436:snm.rar
Мощный тест разогрева процессора и памяти с одновременной проверкой наличия ошибок в их работе для систем на базе AMD Athlon и Pentium 4. Эффективнее чем CPUBurn, бесплатен.

вместе с "S&M" поставь "SpeedFan" (http://www.almico.com/speedfan.php) - компактное, но очень функциональное средство для мониторинга аппаратных частей компьютера. Позволяет считывать напряжения, скорость вращения вентиляторов и температуру с чипов мониторинга.
версия 4.32 - http://overclockers.ru/download?44 или на их сайте

А нет ли проблем с памятью?
Сколько памяти определяет система (узнать можно командой free)?

SWAP назначен?

Если весь день гонять бук на любых задач в KDE, то не виснет, но стоит запустить emerge, как бук виснет (не всегда сразу, обычно не более 10 пакетов ставит) вне зависимости от нагрева.
Вышел из ситуации через монтирование NFS-ом на основной комп и так уже ставлю, что нужно.
