运行 lsmod/（和其他 kmod 相关命令）时出现以下错误：
libkmod: ERROR ../libkmod/libkmod-config.c:489 kcmdline_parse_result: Ignoring bad option on kernel command line while parsing module name: '['
- 我能否以某种方式找出这个模块名称正在被解析的位置？
- 我怎样才能找出造成这一现象的原因？
- 有办法调试这个吗？
笔记：
- 我卸载了所有 nvidia 驱动程序
- 系统：Ubuntu 18.04.4 LTS
- 内核：5.3.0-51-通用

答案1
解决方案是检查传递给内核的命令行
cat /proc/cmdline
然后编辑 grub 文件/etc/default/grub，修复错误的参数并运行sudo update-grub
