[Bug 1103187] Re: xfs left inconsistent after reboot, causing grub to fail
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.

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.
