I have that too... on basically every system with dm-crypt and high
memory.
I just thought it was a known issue of dm-crypt and never really digged
any deeper into it ^^

Also I don't use LVM anymore.


Whenever I write a lot of data it first goes fast (as if some buffer
would first be filled up) and then easily freezes the whole system
(until all data has been encrypted and written).
Sometimes it even freezes stuff which one would assume shouldn't need
any IO (clock applet in the desktop environment or even the mouse
cursor).


Cheers,
Chris.
