Hi,
I added the “memmap” parameter in “/etc/default/grub” to reserve memory as shown below:
GRUB_CMDLINE_LINUX=“crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M resume=/dev/mapper/rl-swap rd.lvm.lv=rl/root rd.lvm.lv=rl/swap rhgb quiet memmap=128M\$0x100800000”
However, when booting, only the parameter “… memmap=128M” appeared. After disabling GRUB_ENABLE_BLSCFG (GRUB_ENABLE_BLSCFG=false), the parameter appeared normally.
Could you please let me know if disabling it is correct method?
Thank you.
