Comment 1 Alexandru Georgescu 2012-12-13 15:58:11 UTC

This was tested on Lenovo Ideapad S10-3.
It also happens with the ATOM-PC build for denzil-next:

http://autobuilder.pokylinux.org/nightly/20121206-2/machines/atom-pc/core-image-sato-sdk-atom-pc.hddimg


The errors appear on the dmesg ouput after the image boots.

So that's the ACPI bug https://www.acpica.org/bugzilla/show_bug.cgi?id=946, closed resolved invalid.

Linux's behaviour is identical to Windows (which is the "real" spec) and conformant to the actual spec (which says that the instructions provided by the BIOS is invalid).
