Скомпилировал ядро Liquorix stable (тоже самое что и Zen), через некоторое время после работы машины (Xeon E5620, Dedicated) (аналогичное происходит на VDS), происходит странное - нагружен процессор на 100%, но не процессорами, а системой (или чем-то другим, объясните мне...т.к. я непонятия не имею что такое «hi». Скриншот: http://data2.floomby.com/files/share/18_3_2013/u6Fa6T2heUq61lsfn84XAQ.png) нагружается он на 100% и так до перезагрузки, отключение всех процессов не помогает, это может случится через час, а может быть через 10 часов, если я правильно понял, это происходит когда идёт нагрузка на диск (может большая, но там не должно быть ничего серьёзного, на ванильном ядре не жаловался) или на что-то системное..может интеррапты? Ядро собирал так, чтобы приоритет был не на скорости, а на качестве работы, стабильности и минимальности загрузки процессора, RAM, SWAP (включены zswap и прочие фичи из zen). Проблема и на i386 и на amd64.
Вопросы:
1. Что такое «hi» в нагрузке процессора? 2. Какие опции ядра могут такое вызывать? 3. Кто-нибудь с таким сталкивался после сборки ядра?
