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:

I have the following problem:

When copying some more *.JPG files by NFS to my N2100 it suddenly

- 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  
  to 30 pictures in one go. (about 2 to 3 MB size each)
  My Setup is a Ubuntu based laptop on one side and the N2100 on 
  the other side.

- It seems not to happen when I don't use Gnome (just cp from 
  command line).
- Is seems not to happen when I use Gnome but just copy about 5 files
  in one go.

- I'm sure it didn't happen in Springtime and before.
