在从 14.04 到 16.04 进行就地 dist-upgrade 之后，我选择用供应商专有的驱动程序替换内核 wifi 驱动程序，以增强信号和吞吐量。驱动程序安装将设备命名为 enp3s0f0（以非常类似 Solaris 的方式）
从那时起，当我进入挂起模式时，我的机器立即取消挂起。
日志如下，但我认为最有趣的部分来自 powersave.log：
Running hook /usr/lib/pm-utils/power.d/wireless false:
Turning powersave for enp3s0f0 off...Error for wireless request "Set Power Management" (8B2C) :
SET failed on device enp3s0f0 ; Operation not supported.
Failed.
/usr/lib/pm-utils/power.d/wireless false: success.
但我不知道接下来该如何进行。
