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

[sudodus]

I have access to one old and slow HP computer, a Probook 6450b with an
Intel i5-M520 CPU. But it seems to be too new to be affected by this
bug. It boots in BIOS mode with this new Groovy iso file.

My son has another and older HP Elitebook, and this bug needed MSDOS
partition table to boot via grub from USB, but its graphics stopped
working some time ago. Maybe I can make it work via an external screen
...

  failure to boot groovy daily  (again)

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..

  ** Expected result

  It boots & is usable
