Title:
  Hibernation throws ecryptfs_encrypt_page errors on Latitude E5420

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  How to repeat:

  I've installed Ubuntu 11.10 on a Dell Latitude E5420. My machine has
  an encrypted home directory, and /home is mounted from a different
  partition on the same hard drive: this might be relevant.

  I prompy my laptop to hibernate by pressing the power button and
  selecting "Hibernate".

  What should happen:

  The machine should go into hibernation and then poweroff. When I
  restart it, my session should be remembered.

  What actually happens:

  Hibernation gets so far and then throws anywhere between a couple and
  over a dozen errors of the form:

  [XXXX.XX] ecryptfs_encrypt_page: Error attempting to write lower page;
  rc = [-Y]

  where XXXX.XX is a dmesg-like timestamp and Y is some small integer.
  These errors appear on a text-only screen i.e. X seems to have already
  shut down.

  The machine then hangs. When I power cycle it (holding power button
  down for 5 seconds then restarting) it starts very quickly -
  suggesting it is coming out of hibernation - but my session has been
  forgotten. There are no open browser windows or applications.

  More information:

  As I don't know exactly what package might be causing this bug then I can't be sure what information to provide, but let me know what diagnostics I can run.
