[Bug 1744357] Re: Bionic 32 bit iso fails to boot

[TJ]

Tested the Xubuntu daily live i386 ISO (2018-01-20) using QEMU/KVM on
16.04 and also couldn't reproduce the boot failure. Selecting "Try..."
mode the system reached the desktop. It did seem to fail to properly
pain the desktop or panels but was fine after "sudo systemctl restart
lightdm".

Title:
  Bionic 32 bit iso fails to boot

Status in syslinux package in Ubuntu:
  New

Bug description:
  Noticed a comment in #ubuntu+1 about an issue booting 32 bit Kubuntu
  early UK 19th January, followed up with some testing of various
  flavour 32 bit iso's.

  First checked with 4.13.0-30 (which I installed from bionic-proposed),
  also tested with 4.13.0-25

  Tested all using gnome-disks and dd.

  These tests were all done with ISO's available from the iso tracker
  for Bionic at 06:30 UTC 19th January.

  These flavours fail to boot 32 bit iso with no comment - all I get is
  a reboot of the machine, time to reboot depending on waiting for
  human/kbd or using Try 'flavour' from the boot menu.

  Kubuntu Bionic 32 bit failed to boot using either gnome-disks and dd.
  Lubuntu Bionic 32 bit failed to boot using either gnome-disks and dd.
  Xubuntu Bionic 32 bit failed to boot using either gnome-disks and dd.

  The following 2 flavours were only checked using 4.13.0-30 and iso's
  were downloaded ~16:30 UTC and dd.

  Ubuntu Mate 32 bit failed to boot using dd.
  Ubuntu Budgie 32 bit failed to boot using dd.

  To test that this wasn't an issue locally I also tested Xubuntu
  17.10.1 32 bit ISO - this booted when created on either bionic kernel
  either with gnome-disks or dd.

  In addition I have grub stanza's (see below) set up for ease of
  booting the Xubuntu Bionic ISO's, these are updated at the same time
  as I zsync Xubuntu ISO's.

  Xubuntu 64 bit from GRUB - booted
  Xubuntu 32 bit from GRUB - failed to boot

  menuentry "XUBUNTU 18.04 32B Daily ISO" {
          set isofile="/boot/grubiso/xubuntu-bionic-desktop-i386.iso"
          loopback loop (hd0,6)$isofile
          linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noswap noeject
          initrd (loop)/casper/initrd.lz
