Bug Description

acer aspire 4752安装了ubuntu16.04 内核4.4一切正常，升级了18.04，内核4.15，发现无法启动无线网卡，具体问题也是点击“开启wifi”，然后开启后，提示wifi已禁用，用热键开启wifi也不行。

$lspci
网卡型号是：Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) (rev 01)
各种方法都尝试了，最后在一个不起眼的角落里找到了方法，如下：

sudo vim /etc/modprobe.d/blacklist.conf

最后加入一行 blacklist acer-wmi #将acer-wmi驱动加入黑名单
重启即可。。。

我的电脑也是这个型号，也遇见了这个问题，我试过到4.9还是正常的，之后的版本全有这个问题，另外我用的是 Manjaro 发行版，网上只搜到了这一个报这个问题的地方。blacklist添加后就能打开wifi了。

It's a type, should be regression.

請找出第一個"壞的"v4.10-rc* kernel.
