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

[Erick Brunzell]

Also seems to effect Dell Latitude E6400 with C2D CPU's and an E6510
with i7 M620 CPU laptops using 20201015 Ubuntu image created with
Startup Disk Creator in 20.04. The same USB with the same image works OK
in my old Intel Desktop so I'm reasonably certain it's hardware
specific.

Typical behavior for these Latitude laptops is needing to press F12
while the BIOS screen is displayed and a boot menu will be displayed.
Doesn't matter if you have USB set as first boot option in BIOS - sort
of a buggy BIOS I guess, but in this case the USB is not even recognized
with a recent 20.10 Live USB inserted.

If I go ahead and boot into an installed Ubuntu system on one of these
effected systems with the USB still inserted a message is displayed
saying:

 "Error mounting /dev/sdb3 at /media/lance/Ubuntu 20.10 amd64: Command-line `mount -t "iso9660" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500" "/dev/sdb3" "/media/lance/Ubuntu 20.10 amd64"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb3,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

If in fact that USB drive is at fault it's odd that it will boot in my
old desktop computer, but I will try a different drive just to be
certain. I'm really at a loss as what else to try at this point.

  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..

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

  ** Expected result

  It boots & is usable
