Sorry, here is some more information on my system: Ubuntu server 10.04 LTS x86_64 with 5 SATA disks configured as a hardware raid (3ware 9550) and several encrypted volumes. A simple "dd if=/dev/zero of=/some/volume/1gb.file bs=1G count=1 oflag=direct" causes enough IO for kcryptd to use 100% load and that once in a while freezes the system.
