[Bug 1851311] Re: loopback command hangs in 2.04 under UEFI

[Cubic PPA]

Thanks.
It worked for me when I put "rmmod tpm" inside the menuentry section, but I didn't have anything above that section.

So it seems "rmmod tpm" must be one of the first things in the config
file.

I wonder if it would work if you put "rmmod tpm" as the 1st line, above
"if loadfont..." ?

I'll try moving it above "menuentry Install" in my config file from
comment number 54,
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1851311/comments/54,
and see if it still works.

(It makes sense that you would want to remove this module as soon as
possible).

Bug description:
  Trying to loop mount ISO.

  Installed grub 2.04 to flash drive in UEFI mode from 19.10
  Flash drive does not boot and gives Out of memory error & no server error. Must load kernel first.

  Re-installed grub from 18.04 to same flash drive using same boot stanza.
  Booted without issue.

  From 18.04
  fred at Bionic-Z170N:~$ grub-install -V
  grub-install (GRUB) 2.02-2ubuntu8.13

  from 19.10
  fred at fred-Z170N-eoan:~$ grub-install -V
  grub-install (GRUB) 2.04-1ubuntu12

  Boot stanza that works in 2.02 but not in 2.04

  menuentry "Focal Live ISO" {
  set isofile="/ISO/focal-desktop-amd64.iso"
  loopback loop (hd0,1)$isofile
      linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile toram noeject
      initrd (loop)/casper/initrd
  }
