A few weeks ago I started seeing error lines on a black screen at the start of the

Their first appearance followed an MB battery change. Nothing seemed broken, and I
took little notice. But now I see the date 20170119, which implies something in
software. google found
https://lkml.org/lkml/2017/4/10/1232, 'PCI IRQ allocation broken' - with
undesirable effects.
That's linked to
https://bugzillakernel.org/show_bug.cgi?id=195319
which is marked as a duplicate of BZ 195311 and closed.
I don't believe the date you are seeing is indicative of anything being wrong.
As a matter of fact, if you do a google search on nsarguments-189 or dsfield-211
you'll come up with a large number of finds such as this one
https://ubuntuforums.org/showthread.php?t=2199573 which has an entry dated January
17th, 2014 and a reference to 20131115/nsarguments-95. So, I suspect the date in
these messages are pointing to the date the module's code was last modified.
Thanks, Ed. Yes, I have seen much earlier reports similar to the first
line I quoted, which wasn't the focus of another recent thread here.
And I think I shall put Heinz's suggestion of compiling a vanilla kernel
on hold :-)
