无法暂停NVMe M.2 SSD
我已经安装了三星Pro 960固态硬盘，这是一个NVMe M.2 Gen 3.0 x 4固态硬盘，但是在Ubuntu 16.04中它冻结试图暂停和恢复。 它在Windows 10中运行正常。

补丁https://patchwork.kernel.org/patch/10212201/将正确修复此问题，它也应该被移植到较旧的内核，所以希望你的NVMe驱动器不需要任何解决方法，它也应该也修复了USB-C检测
NVMe SSD暂停/恢复是一个知道的bug
Launchpad和ArchLinux上已报告此问题。 解决方案是使用sudo powers编辑/etc/default/grub并找到该行：
GRUB_CMDLINE_LINUX_DEFAULT="quiet kaslr acpiphp.disable=1 pcie_aspm=off nloglevel=3 udev.log-priority=3"
您的选项会有所不同，但在双引号之间添加选项acpiphp.disable=1 。
保存文件并运行sudo update-grub
重启然后暂停和恢复将起作用，除非它是一个不同的问题。
acpihp.disable=1做什么用？
根据2013年的内核开发人员的说法，这会禁用ACPI热插拔。 但是，这并不意味着您的计算机上禁用了热插拔。 例如，将USB线重新插入Android手机会让Nautilus按原样查看文件。 还可以通过USB-C ThunderBolt 3连接到笔记本电脑的第二台电视机再循环到Displayport到HDMI适配器，重新组织工作区内的窗口。
