I also noticed that the current 2.6.26 stable kernel with dma patch from
Martin crashes and reported this too Martin. For me the official 2.6.26
kernel does not show this problem. I triggered the problem with copying
about 20 *.jpegs with nfs from my laptop to the thecus.
my letter to Martin:

- It appears to happen when the Gnome file manager is used to display
the source and destination folder, and i try to copy more then 20
