I'm using ecryptfs-utils-48 and kernel-2.6.25.4.
After starting ecryptfsd as root and mounting a dir using any key-module everything is fine and accessible. Now, when I start ecryptfsd as user (so we have ecryptfsd running twice) I get a kernel BUG (see attachment). Also, a problem that seems to be related to the above occurs when I shutdown the VM (even with only one instance of ecryptfsd running). Benedikt
