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

[sudodus]

Hi Chris,

Please test Ubuntu Desktop (standard Ubuntu) Groovy version dated Okt 13
08:36 from zsync,

- '20201013.1' in the testing tracker

$ ls -l groovy-desktop-amd64.iso
-rw------- 1 sudodus sudodus 2894153728 okt 13 08:36 groovy-desktop-amd64.iso

$ sha256sum groovy-desktop-amd64.iso
3b92cb0d427998b5a7f58377d0204ef56e3f21e8748331bef4005f8f244e814f groovy-desktop-amd64.iso

This iso file works for me, also in my son's old HP Elitebook 8560p
(where the current Lubuntu iso file fails).

If the booting is flaky try either to shutdown and wait for several
seconds before booting *or* reboot. (The computer may act differently in
these two cases.)

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
