I did some more testing, and found that the problem does occur on my 
Dell GX-260.  I just didn't happen on the reboot after applying 
updates.  It is possible that the problem is less likely to happen on a 
reboot, than after an initial power-on.  But it does happen on a reboot.

I also updated a Dell GX-240, and the same problem happened there, as
well.

If I boot (even after power-on) an earlier kernel ('-45' or '-47'), the 
problem does not occur.

When I boot a kernel having the problem ('-51' or '-52'), selected as 
the default for a different partition (of the same drive), the problem 
does not occur (even after power-up).  It appears I can reliably boot 
that way.

Title:
  After Installing Updates, system fails to boot on first try

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I installed Lubuntu 18.04 LTS on an i386 machine (Dell GX-270).  After
  installation, it rebooted with no problems.

  I installed all updates, and on rebooting it failed to boot.  The
  screen had unreadable graphics in the top third of it.

  On rebooting again, it booted okay, saying it recovered the journal.

  Sometimes, it takes 3 tries to get it to boot.  Often, it gets most of
  the way into the boot process, then suddenly goes into the GRUB menu.

  I installed this system because my primary partition on the same
  machine started failing to boot much of the time.  This failure
  started happening after applying updates.  I was thinking something in
  the system files might be corrupted.  But the newly-installed system
  has the same symptoms.

  After applying updates, I expected the system to boot successfully
  every time.

  Instead, it always crashes during the boot, or hangs, on the first try
  to boot.  On the 2nd or 3rd try, it will boot.
