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

[Julian Andres Klode]

An easy minimal test case would be appreciated. I guess I could just put
grub into a directory and then tftp boot that inside qemu, and add a
large file in there or something? (or use -vfat on a dir)

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
