使用安装了 Ubuntu 16.04 的东芝 Chromebook，一切正常，直到我合上盖子使其进入睡眠模式。一旦我打开盖子，启动日志中就会出现这种情况

有问题的错误当然是
Jun 06 18:40:16 kernel: ehci-pci 0000:00:1d.0: port 1 resume error -19
唤醒完成后不久，grub 日志就充满了错误，偶尔会打印出“连接反弹失败”之类的内容，然后切换到
Jun 06 18:40:16 kernel: ehci-pci 0000:00:1d.0: port 2 resume error -19
然后几秒钟后切换回“端口 1”。
我只是不知道该如何解释这个问题或者是什么导致了这个问题。
另外，计算机关机速度相当慢，不知道是否与此有关。
