我已将SD卡连接到笔记本电脑,并将其用作家庭分区。当我打开计算机的电源时,到达主文件夹和子目录没有问题,但是当我挂起它并继续时,系统不会读取SD卡。因此它可能会冻结,迫使我重新启动计算机以使所有内容重新工作。
一些有用的信息是:
- MacBook Air 2016
- macOS Sierra和Ubuntu 17.04双启动
- (在16.10上也发生了相同的问题)
一些进一步的信息:

另外,主要区别在于,在挂起之前lsblk
显示我的sdb1
设备(已将我的SD卡安装为/home
)。唤醒后lsblk
命令不显示我的SD卡,并且我无法访问文件/home
夹中的文件。我也无法重新连接SD卡;无法识别。
syslog –最新的暂停发生在45263行的“ May 9 22:56:01”。
有趣的部分似乎是:
May 9 22:56:25 MacBookAir kernel: [ 5883.035573] PM: Finishing wakeup. May 9 22:56:25 MacBookAir kernel: [ 5883.035575] Restarting tasks ...

如果您需要保密,最好在硬盘上具有/ home目录并对其进行加密。

@ user258532我的隐私没有问题。我使用SD内存是因为我有m.2 sata ssd,它具有128 GB内存,其中60-70%属于macOS。

在挂起/唤醒之前和之后,您是否在lsusb输出中看到任何变化?

没有名为pm-suspend.log的日志文件。但是,我将syslog文件复制为pastebin。
