[Bug 1886148] Re: failure to boot groovy daily

[C.S.Cameron]

Creating a Live Only USB using 20.10 20200924 and 12.9.3 ave similar
results to the Persistent install.

Worked fine in BIOS mode.

Gave initramfs unpacking error in UEFI mode plain persistent boot.

Gave initramfs unpacking error in UEFI mode persistent boot with
nomodeset edit, but quickly continued booting to desktop.

Safe Graphic Mode boot also had initramfs unpacking error in UEFI mode
but continued on to Language screen and beyond.

This is similar to my experience trying to boot ISO files directly, but
I only recall the unpacking error that continued to boot with the Live
only USB.

  The ISO was written twice to two different thumb-drives. Same issue
  each time on same boxes.

  On a number of boxes it’s wanting me to download aka
  https://bugs.launchpad.net/ubuntu-cdimage/+bug/1883040 however it’s
  done that on boxes not impacted by that bug, which makes me think
  thumb-drive/squashfs errs related.  Also results of boot appeared
  different on varying boxes (inconsistent; dc7700 reported no thumb-
  drive; d755-5 also did that sometimes, sometimes it got to wanting to
  download - those two boxes were impacted by prior report; the
  remaining boxes were more consistent in response..; but if trouble
  reading data on thumb-drive then the slower boxes (dc7700/d755-5) may
  have more issues & thus be less consistent?)

  I'll file this as a bug report so I can close my failed QA-tests, but
  I'm considering changing the status to 'incomplete', and re-testing
  tomorrow, OR it needs me to re-write ISO from a different box to a
  third-thumb-drive as I don't think I've ruled out media issues given
  Leok's report.
