This message means that your machine's bios is querying the operating system to determine if it is Linux, and this query is being ignored by the kernel. The kernel labels this as a bug in the bios (not a bug in Linux) because that query is no longer supported, since Linux ACPI functionality is roughly equivalent to that in other operating systems.
As such, I'm marking this bug invalid. ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1341021 Title: [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored Status in “linux” package in Ubuntu: Invalid Bug description: [ 0.130699] ACPI: Executed 1 blocks of module-level executable AML code [ 0.133984] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-3.16.0-3-lowlatency 3.16.0-3.8 ProcVersionSignature: Ubuntu 3.16.0-3.8-lowlatency 3.16.0-rc4 Uname: Linux 3.16.0-3-lowlatency x86_64 ApportVersion: 2.14.4-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC1D0p: caravena 2878 F...m pulseaudio /dev/snd/controlC1: caravena 2878 F.... pulseaudio /dev/snd/controlC0: caravena 2878 F.... pulseaudio CurrentDesktop: GNOME Date: Fri Jul 11 19:55:41 2014 HibernationDevice: RESUME=UUID=360bd2d2-4f44-4311-86d6-4781ac81ee87 InstallationDate: Installed on 2014-04-27 (75 days ago) InstallationMedia: Ubuntu-GNOME 14.04 LTS "Trusty Tahr" - Release amd64 (20140416.2) MachineType: SAMSUNG ELECTRONICS CO., LTD. 530U3C/530U4C ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-3-lowlatency root=UUID=13144268-2374-4154-83f1-c35d81306190 ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.16.0-3-lowlatency N/A linux-backports-modules-3.16.0-3-lowlatency N/A linux-firmware 1.132 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/15/2013 dmi.bios.vendor: Phoenix Technologies Ltd. dmi.bios.version: P14AAJ dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: SAMSUNG_NP1234567890 dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: FAB1 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: 0.1 dmi.modalias: dmi:bvnPhoenixTechnologiesLtd.:bvrP14AAJ:bd04/15/2013:svnSAMSUNGELECTRONICSCO.,LTD.:pn530U3C/530U4C:pvr0.1:rvnSAMSUNGELECTRONICSCO.,LTD.:rnSAMSUNG_NP1234567890:rvrFAB1:cvnSAMSUNGELECTRONICSCO.,LTD.:ct9:cvr0.1: dmi.product.name: 530U3C/530U4C dmi.product.version: 0.1 dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD.
