![内核更新后 ath9k 驱动程序不工作](https://linux22.com/image/1159273/%E5%86%85%E6%A0%B8%E6%9B%B4%E6%96%B0%E5%90%8E%20ath9k%20%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E4%B8%8D%E5%B7%A5%E4%BD%9C.png)
我在 Ubuntu-Gnome 16.04 上,安装了两个内核版本,分别是 4.15 ( 4.15.0-24-generic
) 和 4.13 ( 4.15.0-24-generic
)。当我启动到较旧的版本 (4.13) 时,一切正常。但在内核更新(启动到 4.15)后,驱动程序未声明 WiFi 适配器,驱动程序未加载。尝试通过手动加载驱动程序modprobe ath9k
失败,提示未找到驱动程序。以下是 的输出dkms status
:
bbswitch, 0.8, 4.13.0-43-generic, x86_64: installed
bbswitch, 0.8, 4.13.0-45-generic, x86_64: installed
bbswitch, 0.8, 4.15.0-24-generic, x86_64: installed
我觉得驱动程序没有出现在此列表中很奇怪ath9k
。此列表是在启动到正常工作的 4.13 内核时获取的。问题:
- 这是为什么?
- 如何在启动较新的 4.15 内核时加载驱动程序?
