Kernel error messages

[Anne Wilson]

On this laptop there are many instances of messages like this:

[    2.699064] ACPI Error (psargs-0359): [ ...:  1 Time(s)
    [    2.699069] ACPI Error (psparse-0537):  ...:  1 Time(s)

Is this something I must simply ignore, or is there anything that can be done 
about it?
