Hi Mike - I'm surprised to see this part of the kernel crypto API having
problems.  eCryptfs' use of the kernel crypto API and AES-128 (what
encrypted home uses) has been heavily tested and I don't recall seeing
any problems like this before.

The first thing that comes to mind is hardware crypto acceleration.  Can
you tell us a little more about your processor and/or any hardware
crypto acceleration cards you may have?
