openEuler 20.03 LTS SP3系统 DF723 FT2000+ 标准版本4.19.90内核编译安装后不能启动故障 exiting boot services

本文主要是介绍openEuler 20.03 LTS SP3系统 DF723 FT2000+ 标准版本4.19.90内核编译安装后不能启动故障 exiting boot services，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

标准版本内核编译过程

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.19.90.tar.gz
tar -xf linux-4.19.90.tar.gz
cd linux-4.19.90
make defconfig
make -j64
make modules_install
make install

故障现象

重启后，卡在 EFI stub: Exiting boot services and installing virtual address map...

故障分析

经过实验，已知采用系统自带的config文件（config-4.19.90-2112.8.0.0131.oe1.aarch64）可以正常引导启动。对比config-4.19.90-2112.8.0.0131.oe1.aarch64 与 make defconfig 生成出来的.config文件，发现关键差异

实验1：添加一项：CONFIG_ARCH_PHYTIUM=y

测试重新准备干净的源码，make defconfig后，手动在.config配置

CONFIG_ARCH_PHYTIUM=y

重新编译，安装有以下报错

实验结果（失败）

仍然卡在 EFI stub: Exiting boot services and installing virtual address map...

原版的代码并没有CONFIG_ARCH_PHYTIUM的定义及应用

并且make之后，编译器自动去掉了这个无效的配置

实验2：采用系统默认config，make以后对比差异

[root@localhost yeqiang]# rm linux-4.19.90 -rf
[root@localhost yeqiang]# tar -xf linux-4.19.90.tar.gz 
[root@localhost yeqiang]# cp /boot/config-4.19.90-2112.8.0.0131.oe1.aarch64 linux-4.19.90/.config
[root@localhost yeqiang]# cd linux-4.19.90
[root@localhost yeqiang]# make -j64

差异较多，重点筛选ARM64相关差异，调整后，与原来的defconfig差异如下

重新基于defconfig，操作上述差异修改

实验结果（失败）

仍然卡在 EFI stub: Exiting boot services and installing virtual address map...

说明关键配置没找到或者不全，后续有空再继续。

简单的解决方案

方案一：使用openEuler自带的源码及内核配置编译（稳妥）

参考：https://blog.csdn.net/hknaruto/article/details/129360777

方案二：基于官网4.19.90版本+系统自带的内核配置编译

注意：openEuler 20.03版本内核与标准版本有较大差异，部分配置是无效的，如CONFIG_ARCH_PHYTIUM

参考过程

wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.19.90.tar.gz
tar -xf linux-4.19.90.tar.gz
cd linux-4.19.90
cp /boot/config-4.19.90-2112.8.0.0131.oe1.aarch64 .config
make -j64
make modules_install
make install
