### **在安装P4-SDE过程中遇到部分问题，猜测是因为内核版本太高，特此记录   降级linux内核版本:** ###

### **第一步./p4studio\_build.py --use-profile p416\_examples\_profile安装依赖环境中的在加载bf-driver驱动的时候会出现错误:** ###

### **出现的错误为 :** ###

### **ar: \`u' modifier ignored since \`D' is the default (see \`U')** ###

### **error: macro "access\_ok" passed 3 arguments, but takes just 2   'access\_ok' undeclared (first use in this function)** ###

### **于是查看了早期的内核版本与当前使用的内核版本的access\_ok函数的区别，可见一斑；** ###

###  **早期内核版本linux-image-3.10.87-10-generic** ###

### **现在正在使用的内核版本linux-image-5.0.0-37-generic** ###

### 发现问题所在，当前版本内核太高 ###

### 接下来就是准备对Linux的内核进行降级了 ###

### **`vi ~/etc/apt/sources.list`** ###

**![format_png][]**

### **root模式下进入文件夹，对文件备份** ###

### **`deb http://security.ubuntu.com/ubuntu trusty-security main`** ###

**![format_png 1][]**

### **在最后一行添加软件源地址** ###

### **`apt-get update`** ###

**![format_png 2][]**

### **访问源列表里的每个网址，并读取软件列表，然后保存在本地电脑** ###

### **查询列表中可更新的内核：****`sudo apt-cache search linux-image`** ###

**![format_png 3][]**

### **安装4.4版本内核: `apt-get install linux-image-extra-4.4.0-109-generic`** ###

**![format_png 4][]**

### **查看是否安装成功: `dpkg -l |grep linux-image`** ###

**![format_png 5][]**

### **进入grub文件：`vim /etc/default/grub`** ###

**![format_png 6][]**

### **修改文件如下：`Advanced options for Ubuntu>Ubuntu, with Linux 4.4.0-109-generic`** ###

**![format_png 7][]**

### **更新grub: `update-grub`** ###

### **![format_png 8][]   重启后重新查看内核版本，发现已经完成内核降级: `uname -a`** ###

**![format_png 9][]**
