目前只测试了ubuntu
进入grub
vim /etc/default/grub按i进入编辑模式找到GRUB_CMDLINE_LINUX=
GRUB_CMDLINE_LINUX=" vga=792 console=tty0 console=ttyS0,115200n8 net.ifnames=0 noibrs nvme_core.io_timeout=4294967295 nvme_core.admin_timeout=4294967295 iommu=pt crashkernel=0M-1G:0M,1G-4G:256M,4G-64G:384M,64G-512G:512M,512G-:1G crash_kexec_post_notifiers=1"
把下面这行代码修改以下
crashkernel=0M-1G:0M,1G-4G:256M,4G-64G:384M,64G-512G:512M,512G-:1G crash_kexec_post_notifiers=1"
改为
GRUB_CMDLINE_LINUX=" vga=792 console=tty0 console=ttyS0,115200n8 net.ifnames=0 noibrs nvme_core.io_timeout=4294967295 nvme_core.admin_timeout=4294967295 iommu=pt crashkernel=no"按Esc输入:wq保存
更新并重启
sudo update-grub
sudo reboot总结恢复了256M 1.8G 剩下的不折腾了
