Comment 35 for bug 911507

I also have 12.04 and see many errors like these:

Sep 7 21:53:01 CCCx kernel: [ 1031.641254] Either the lower file is not in a valid eCryptfs format, or the key could not be r
etrieved. Plaintext passthrough mode is not enabled; returning -EIO
Sep 7 21:53:01 CCCux kernel: [ 1031.641340] Valid eCryptfs headers not found in file header region or xattr region, inode 8395
690

then my pc reboots, and I see these during boot.

Sep 7 21:56:35 CCux kernel: [ 10.858208] EXT4-fs (sdb1): ext4_orphan_cleanup: deleting unreferenced inode 8388879

not sure if this is what crashes my system, but the messages are the last things I see in my syslog each time I crash
