что-то подозрительное в моем журнале ядра - “ПРЕДУПРЕЖДЕНИЕ: ЦП: 0 PID: 192” трассировки вызовов

Это, кажется, не критическая проблема, но я хотел бы получить некоторое понимание на этом предупреждении, что я добрался этим утром при начальной загрузке моего ноутбука.

Я всегда удаляю "тихий" флаг из ядра в личинке, которая является, почему я видел предупреждающее сообщение. Это заставляет мой ноутбук зависнуть приблизительно в течение секунды только и затем загружается обычно. Тем не менее мне не нравится нечистый журнал начальной загрузки =D
