大家帮我看下啊

Ubuntu 16.04 LTS 4.8的内核降级成4.6的内核

1. Ubuntu 16.04 預裝 Linux kernel 4.4
1-1. https://wiki.ubuntu.com/XenialXerus/Rel ... kernel_4.4
Ubuntu 16.04 LTS is based on the long-term supported Linux release series 4.4.

2. Linux kernel 4.8 是 HWE Stack
2-0. HWE Stack 套件是 linux-image-generic-hwe-16.04 版本是 4.8.0.49.21
http://packages.ubuntu.com/search?suite ... chon=names
套件 linux-image-generic-hwe-16.04
xenial (16.04LTS) (kernel): Generic Linux kernel image
4.8.0.49.21 [security]
2-1. https://wiki.ubuntu.com/Kernel/RollingL ... k#Proposal
Desktop installs will continue to offer the HWE Stack option only and default to it.
2-2. https://wiki.ubuntu.com/YakketyYak/Rele ... kernel_4.8
Ubuntu 16.10 is based on the Linux release series 4.8.
2-3-1. 3. 在 Linux kernel 4.8 與 Linux kernel 4.4 之間 並沒有 Linux kernel 4.6
2-3-2. 意思是 Linux kernel 4.6 並非 Ubuntu 16.04.02 的 穩定版本

3. 什麼原因 你必須降級為 Linux kernel 4.6
3-1. 如何降級為 4.6 ?

[nicejack]

我现在要做一个芯片的驱动;但是拿不到这个芯片的资料;只有一个这个芯片的二进制文件;这个二进制文件是4.6编译的

[nicejack]

会不会是系统兼容高版本的好些;兼容低版本的就差很 多啊;那我把高版本的删掉;会不会好点啊

您的处理器属于 SkyLake 微架构，比较新。内核当然越新越好。关于有点卡的问题，您可能遇到了一些已知问题，建议到 https://bugzilla.kernel.org ， https://bugs.freedesktop.org 这几个地方逛一逛。不过就算找到了相似的问题，解决方案也多半是使用最新的内核。

[nicejack]

但是在另外和我配置一样的电脑上装的4.6和4.4内核就不会出现这样的情况

[poloshiao]

这个二进制文件是4.6编译的

1. 你可以下載
1-1. Ubuntu 16.04 的 ISO
https://wiki.ubuntu.com/XenialXerus/ReleaseNotes/16.04
1-2. 或 Ubuntu 16.04.1 的 ISO
https://wiki.ubuntu.com/XenialXerus/Rel ... es/16.04.1
來安裝 Ubuntu 16.04
1-3. 安裝完成 或 日後更新 就預設不會安裝 套件 linux-image-generic-hwe-16.04 （除非你手動安裝)
1-4. 安裝後 把 整個 Ubuntu 16.04 系統 全部備存
然後 安裝 linux-kernel 4.6
1-5. 注意 從 Linux 官網下載來安裝 跟 從 Ubuntu 官網下載來安裝 的 Linux kernel 是不一樣的

在另外和我配置一样的电脑上装的4.6和4.4内核就不会出现这样的情况

2. 補充
如果 你直接下載 Ubuntu 16.04.2 或 以後版本的 ISO 來安裝
預設就會安裝 套件 linux-image-generic-hwe-16.04
2-1. 這個時候的 Linux kernel 版本 更新 請參閱
