[Bug 1878541] Re: Grub fails to load kernel from squashfs if mem < 1500mb

[Dimitri John Ledkov]

Note, the Testscript specifies 512MB which is quite small.
Previously, we wanted to ensure that amd64 reference target is "a typical NUC with TPMv2.0 and secureboot", at the time typical NUC models had 2GB of ram.

What is the target minimum ram usage we must achieve?

Bug description:
  Booting a uc20 system fails early currently. The image used was:
  http://cdimage.ubuntu.com/ubuntu-core/20/beta/20200513.2/

  Attached is a screenshot of the debug output.

  This appears to be some sort of regression with grub in 20.04 or with
  UEFI grub - this used to work in uc18.

  Note that there is memory < 1500mb
