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
