[期望结果]：
1.配置crashkernel参数成功
[实际结果]：
1.cmdline中有两个crashkernel的配置
# cat /proc/cmdline
BOOT_IMAGE=(hd0,msdos1)/boot/vmlinuz-4.19.91-23.4.an8.x86_64 root=UUID=169a0746-c62d-49a2-bd6b-0eaec098d42c ro crashkernel=512M rhgb quiet crashkernel=0M-2G:0M,2G-8G:192M,8G-:256M

[复现概率]：必现
问题重现步骤1.修改/etc/default/grub.cfg文件，crashkernel=512M
GRUB_CMDLINE_LINUX="crashkernel=512M rhgb quiet"
2.grub2-mkconfig -o /boot/grub2/grub.cfg
3.reboot,重启后
cat /proc/cmdline


附注这个环境在配置crashkernel前，cmdline中已经有了两个crashkernel，
# cat /proc/cmdline
BOOT_IMAGE=(hd0,msdos1)/boot/vmlinuz-4.19.91-23.4.an8.x86_64 root=UUID=169a0746-c62d-49a2-bd6b-0eaec098d42c ro crashkernel=auto rhgb quiet crashkernel=0M-2G:0M,2G-8G:192M,8G-:256M
