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

[sudodus]

Hi Chris,

There seems to be a difference between the first boot and the subsequent
boots in your

hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

It might depend on the creation of the ext4 partition behind the image
of the iso file, which happens only in the first attempt to boot.
Another difference is that the partition is available for reading and
writing at once in the following attempts to boot.

If you have the time, you could wipe the whole USB drive (with mkusb,
slow process) and then clone from the current iso file again, and when
booting add the boot option 'nopersistent' before continuing to boot. A
more convenient method would be to replace the cloning with creating a
'nopersistent' boot drive using mkusb-plug (but it replaces 'quiet
splash' with 'nopersistent').

This way, the drive should look the same during all subsequent boots.
The question is: will the computer boot every time or fail every time?
Or will there still be differences between the boot attempts?

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
