as per your : [ 0.000000] Your BIOS doesn't leave a aperture memory hole [ 0.000000] Please enable the IOMMU option in the BIOS setup [ 0.000000] This costs you 64 MB of RAM ... [ 0.338295] mtrr: your CPUs had inconsistent variable MTRR settings [ 0.338296] mtrr: probably your BIOS does not setup all CPUs.
Hence, as per http://support.asus.com/download.aspx?SLanguage=en&m=M4A89GTD%20PRO/USB3&os=29 an update is available for your BIOS (3029). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-3029 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1103187 Title: xfs left inconsistent after reboot, causing grub to fail Status in “grub2” package in Ubuntu: Invalid Status in “linux” package in Ubuntu: Incomplete Bug description: take a 12.10 with XFS root partition containing the /boot/ tree dpkg-reconfigure grub-pc ; sync reboot (either by command, or by menu) diverse error messages + grub rescue + /boot/ is partially accessible boot UBUNTU 12.10 pendrive + choose "try Ubuntu" + open a terminal sudo -s; mkdir foo; mount [the XFS root partition] foo; umount foo reboot into the "original" Ubuntu is NOW successful It appears that the kernel xfs filesystem driver leaves the fs in an inconsistent state even after a sync. That is corrected by a journal playback done either via having the kernel mount or running fsck, but grub does not use the xfs journal. --- ApportVersion: 2.6.1-0ubuntu10 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: prohlep 1969 F.... pulseaudio /dev/snd/controlC0: prohlep 1969 F.... pulseaudio /dev/snd/seq: timidity 1533 F.... timidity CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
