I have been usingused Linux on my PC for a long time. Some time recently, there is a new kernel error message which appears on the text console.

It also appears as a message in red in journalctl -p err. It did not appear like this before.

Question: Why did this change?

Notice: I am writing this as a very general question, in order to host the answer below.

Notice: ACPI error messages on specific systems might have a more specific causecauses, problems, and solutions. For example, see this questionthese two questions: ACPI BIOS Error / AE_NOT_FOUND

  1. ACPI BIOS Error / AE_NOT_FOUND
  2. ACPI Exception: AE_NOT_FOUND infinitely on startup

My error messages are:

ACPI Error: [DSSP] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359)
