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

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
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.
Perhaps coincidentally, one of my pci devices (onboard audio) unexpectedly got
disabled when I changed a video card. Details on the rpmfusion list. The audio is
working again after a BIOS edit, but I'm still seeing the errors above in dmesg.
The BIOS manual suggests that ACPI will override the BIOS setting. I'm confused.
