I can reproduce the general protection fault mentioned in comment #44 pretty easily.
I ftraced the eCryptfs code while triggering the crash and don't see much going on other than a lookup(), the eCryptfs inode initialization functions being called, and the a call to ecryptfs_readpage(). This reminded me of an upstream race condition that I fixed not too long ago. I'm backporting those patches to the natty kernel to give it a shot.
The patches are already in the oneiric kernel so if someone has successfully reproduced this on oneiric, please speak up.
