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

[Claudio Matsuoka]

Chris Coulson's patch should also solve the problem that breaks install
on the Thinkcentre m920s with TPM enabled. The last printed message when
booting with grub debug enabled is the type of the loopback file, and
nothing happens after that. It finishes installing if you rmmod tpm.

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
