Title:
  iscsi root with or without auth fails to boot

Status in “open-iscsi” package in Ubuntu:
  Fix Released
Status in “open-iscsi” source package in Natty:
  Fix Released
Status in “open-iscsi” source package in Oneiric:
  Fix Released

Bug description:
  Stable release update justification:

  IMPACT: Some systems with their root file system on iSCSI fail to
  boot.

  DEVELOPMENT BRANCH: open-iscsi 2.0.871-0ubuntu6 fixes this bug as
  described in comment 15.

  PATCH: http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/oneiric
  /open-iscsi/oneiric/revision/32

  TEST CASE: Only some iSCSI-based systems suffer from this; I expect
  there are race conditions involved.  Those affected would fail to boot
  in some manner similar to that described later in this bug
  description, and this change should make them boot successfully.

  REGRESSION POTENTIAL: Strictly confined to systems using iSCSI.  I
  tried hard not to make any additional assumptions in this patch; if it
  works, it should be safe.

  Original report follows:

  Natty alpha3 test iso's for ubuntu-server amd64 (haven't tested i386
  yet).

  Running the iscsi auth and unauth tests.

  Installation is fine. Before reboot, I copy vmlinuz and initrd.img to
  tftp server.

  System boots ok, till it gets past apparmor, then it has issues, I
  assume something with bringing up networking is wiping out the iscsi
  config?

  Screen shows:

  fsck version ......
      /dev/sda1  clean, 52412,491526 files    262116/1965824 blocks
  * Starting AppArmor profiles     [ OK ]
