I hope that this was the extent of the 'corruption'. You shouldn't have
been able to reach any of your existing files with encrypted names and
any new files would have unencrypted names. When rebooting into an older
kernel, you could see two files with same name because one had file name
'foo', which was unencrypted in the lower file system and the other was
the encrypted version of file name 'foo' in the lower file system.
getdents() would return 2 files of the name 'foo', but only one could be
looked up.

I imagine that if you remove any newly created files under the
2.6.36-rc{1,2} kernels (they should be easy to locate in the lower file
system because the file names don't start with ECRYPTFS_FNEK_ENCRYPTED
and are plaintext), everything should be back to normal.

I am sorry for the inconvenience.
