I have the latest BIOS from Dell. I am frankly quite ignorant of ACPI, but the errors look different to me.

Hi
What type of DELL system? It’s the acpi DSDT table, if everything is working (Fn keys for vol, wifi, brightness, lid switch etc), you should be fine… You could perhaps look at raising a kernel bug, but think they will advise to talk to the DELL folks…
FWIW, I have a DELL Inspiron 5555 with A12 firmware rev 65.12 and don’t see any acpi errors.

All the function keys etc. seem to be working. So should I suppress
those events in the log?
Hi
Perhaps you could as long as everything is working as expected, just
keep an eye out for a BIOS update, if it starts playing up with later
kernels you might need to re-enable…

After looking at the logs, it appears I have been getting this error for a while, they were just not displayed.
Exactly, so the ACPI errors have always been there, 4.9 just seems to do a “better”(?) job in displaying them on startup.
Such warnings/errors are pretty common and as long as you don’t experience any serious problems, just ignore them.
Although being a standard, ACPI is the one often being ignored (on purpose?) by some (many, most?) vendors, just think of those funny kernel paramters sometimes needed to “trick” the BIOS so it “thinks” you are running some Windows OS in order to get access to functions otherwise being blocked.
This feels like a pretty sweeping statement. I’m not sure I’ve ever seen ACPI errors before. It would seem that some work went into fixing ACPI errors for 4.9
