Dell Laptop (E6420) using Fedora's default-install dm-crypt
configuration.  The performance hit was in how long it took to copy
~300GB of data from a USB (or eSata) drive.  When I did a similar copy
on an unencrypted ThinkPad it took a fraction of the time that it took
to copy it on the encrypted Dell.  Same Data.  The only differences were
the ThinkPad v. Dell, and encrypted v. non-encrypted.  Even the copy
method was using the same, on the same base OS.

I just dont recall if I had upgraded to 2.6.40 before or after copying
all the data....
