[Bug 1899308] Re: failure to boot groovy daily (again)

[sudodus]

@ everybody,

In the light of the lasts findings, questions and suggestions, I did
some more tests, this time with yesterday's Xubuntu Groovy iso file,
that failed booting yesterday.

I think I started testing the cloned USB drive in the Lenovo V130 (which
worked), and continued testing in the HP Elitebook 8560p.

Anyway, today I started with a cloned drive (without prior wiping) and
testing booting in the HP Elitebook 8560p.

- Successful boot first time, and an ext4 partition was created
- Failed boot after that: the drive was not recognized (could be repeated)

Then I created a 'nopersistent' drive with mkusb-plug in the same drive
(without prior wiping) and testing booting in the HP Elitebook 8560p.

- Successful boot first time. No ext4 partition was created
- Successful boot after that (could be repeated)

I conclude that the crucial thing is the existence of the ext4 partition
(and maybe other things associated with it - corruption, backup gpt
table at the tail end of the drive ...)

Title:
  failure to boot groovy daily  (again)

Status in Ubuntu CD Images:
  Fix Released
Status in cd-boot-images-amd64 package in Ubuntu:
  Confirmed

Bug description:
  This is either a duplicate or return of
  - https://bugs.launchpad.net/ubuntu-cdimage/+bug/1883040
  - https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148

  Most probably "groovy daily won't boot anymore on some older BIOS
  boxes" or the 1883040 bug, as it's impacting only my older slow boxes
  (but it's also different).

  thumb-drive has been successfully used in QA live & install tests,
  however it won't boot on

  hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
  hp dc7900 (c2d-e8400, 4gb, intel 4 series integrated i915)

  The last timing issue also impacted d755-5 (older dell optiplex 755)
  when dc7700 was impacted, but that booted successfully this ISO.

  I see thumb-drive flash as it tries to boot, eventually it stops
  flashing, but no boot. At least 6 attempts made to boot, thumb-drive
  being tested on another 2x d755 boxes..

  (ISO written by mkusb/dus & gnome-disks [#11] is identical)

  ** Expected result

  It boots & is usable
