Две паники ядра за две недели, что не так?

Question

У меня было две паники ядра за две недели на моем Macbook.

Есть идеи, что случилось?

Вот мой отчет:

Answer 1

Это нарушение прав доступа в режиме ядра драйвера Bluetooth. Это вызвано неправильным доступом к памяти из режима ядра, что является серьезным недостатком в программировании драйвера. (В частности, процессор попытался прочитать память по адресу 0xffffff8015d47000, который не был отображен).

К сожалению, нет ничего конкретного, что вы можете сделать, чтобы предотвратить этот тип сбоя, однако, если ошибка продолжает возникать, вы можете обнаружить, что отключение устройств Bluetooth сделает систему более стабильной.

Тем временем, убедитесь, что аварийные дампы отправляются обратно в Apple, и в какой-то момент они смогут исправить и выпустить патч для сломанного драйвера.
