I recently noticed this error in /var/log/kern.log.1 :

And some of these :

Sep  3 09:40:38 simon-laptop kernel: [54047.132640] ecryptfs_readpage: Error decrypting page; rc = [-4]

Since then, I get a lot of those :

Sep  2 17:19:39 simon-laptop kernel: [194789.437221] Valid eCryptfs headers not found in file header region or xattr region
Sep  2 17:19:39 simon-laptop kernel: [194789.437229] 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

Those error occurred after I ran out of space in my home. I don't know
if it worth mentioning but when this occurred I was running this kernel
: Ubuntu 2.6.35-19.25~lucid1-generic 2.6.35.3. I am now back to the
default Ubuntu kernel : Ubuntu 2.6.32-25.43-generic 2.6.32.21+drm33.7
and I still have the error.
