"EFI Memmap Is Not Enabled" on Boot Screen

[Eddie Paul Litz]

On Linux 4.19.1, on the Boot Screen, a text appears showing "EFI Memmap is not Enabled". Is that just saying UEFI Mode is disabled & it's nothing to worry about or if it's not, how do I enable EFI Memmap in Ubuntu Linux?

G'day Eddie Paul

Do you have a Grub Menu with your Ubuntu?

If so, take the option after Ubuntu eg "Advanced Options for Ubuntu" and click - there should be a couple of entries for older kernels, likely 4.15.0-38 or 4.15.0-36.

I take it that by

On Linux 4.19.1

... you are referring to having upgraded your Kernel?

Try one of the older kernels and see if you still get that message.
