git - Linux 最新稳定编译：不能代表对 vmlinux-gdb.py 的更改：

问题描述

问题：

我对内核版本优先级的了解：

  1. 使用您自己的发行版内核（不可能：太慢了）
  2. 使用最新的稳定内核
  3. 使用最新的 LTS 内核

我试过的：

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
git checkout -b stable v5.1.2
cp /boot/config-`uname -r` .config
yes '' | make oldconfig
make -j `getconf _NPROCESSORS_ONLN\' deb-pkg LOCALVERSION=-fab

这给了我以下错误：

dpkg-source: error: cannot represent change to vmlinux-gdb.py:
dpkg-source: error:   new version is symlink to /home/fab-user/Documents/Source/linux/scripts/gdb/vmlinux-gdb.py
dpkg-source: error:   old version is nonexistent

在以下完整输出中：

make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-fab

所以我最终做了：

git checkout -b v4.19.38 v4.19.38

这给了我高达 10MB/S 的速度，而不是我的发行版的标准内核的 12Mbps，而且效果很好，但如果我想保持 WiFi 驱动程序的全速，我需要每 24 小时重新启动一次机器。

问题：

我注定要留在 4.19.38 吗？
有没有办法让 4.19.39-5.12 版本永久工作？

解决方案

只需删除vmlinux-pdb.py符号链接即可scripts/gdb/vmlinux-gdb.py为我解决问题。

所以在内核源代码的根目录下

$ rm vmlinux-gdb.py
