This started to happen after the second ACPI merge which was for 2.6.23-rc2.

Perfect is the enemy of good

It appeared after new Embedded Controller code was merged into ACPI. It might as well be just a debug message or a remainder to add support for new queries (whatever these are), but I do not know. The message itself seems harmless.

Meelis Roos ([email protected])

This _is_ a debug message. EC asks us to perform query which was never defined in DSDT. Previously I thought it would be rare error report, but now it seems that every machine has at least one unregistered query... It is not a functional regression, as we just ignored errors from query execution before.

Len already has a patch to remove this printk.

Regards,
Alex.
