Title:
  xfs left inconcistent after reboot, causing grub to fail

Status in “grub2” package in Ubuntu:
  Invalid
Status in “linux” package in Ubuntu:
  Confirmed

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.
