Comment 184 for bug 509180

Linux host 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux
New Thinkpad X220, quite fresh install, all updates, using Docking station, disk never filled up
I got aware because Skype (comes up at startup) always asked me for the license agreement again, and again.

Then I found:
Feb 27 22:53:54 CS-TP kernel: [ 99.745589] Valid eCryptfs headers not found in file header region or xattr region
Feb 27 22:53:54 CS-TP kernel: [ 99.745602] Either the lower file is not in a valid eCryptfs format, or the key could not be retrieved. Plaintext passthrough mode is not enabled; returning -EIO

The I tried to remember what might have caused this...
After I tried to hibernate (what as I read now is not working with ecryptfs ?) the system could neither hibernate nor shut down anymore and always came back to the login screen. Then I had to switch it off, because I was in a hurry. Not really sure what caused the problem.
During this up and down cycle one can see different error messages.

There are 3 zero byte files, I can provide more information...
