我的 MacBook Pro 开机时间越长，运行速度就越慢。我收到了内核警告。
有些（但不是全部）重置与交流电源连接和断开相关。我不认为警告与此相关。（我怎么知道？）
这些错误是什么？它们的原因是什么？
这会损坏驱动器或破坏数据吗？看到什么会促使出现这些情况？

答案1
这看起来可能是原因：https://bugs.launchpad.net/linux/+bug/576601
我发现您没有安装 Apple EFI 固件更新 1.7，该更新已知会导致总线错误，从而由于更新启用的 SATA2 3Gps 支持存在故障而损坏数据。排除了这种情况。或者您的芯片组可能比平均水平更差？
是否有人有关于 nvidia 中断处理（据称已针对 MBP7,1 进行了修复，但可能不是你的）或有故障的 SATA 错误的内核错误日志？
