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.
