ads8272 SEC problem on 2.4.18

I am trying to get the SEC engine running on a ads8272
but i am completely stuck now. (It feels like the problem
we saw on this list last month, but there is still no solution
to that issue yet.

Quick Problem description:
  initialize seems, ok, yet when i feed a single
  dpd (for DES EU) into channel 0, the engine
  seems to stuck during fetch. Nothing happens.

- Can someone help me out? (Not sure if this is the right list for this?) 
- Do (open) sources for the SEC1 (motorola/freescale) engine exist for vanilla linux?
  (I know of Arabella, but they are neither open nor for vanilla linux) 


P.S. some more details below
more info:
 - i hopefully initialized it correctly
 - prepared a dpd
 - wrote it into fetch register
 - see that something happens: CurrentDescriptorPR changes
 - boing, that's it... no more

some dumps:
 Before writing the fetch register:
  CryptoChannelConfigRegister (f0042008), 0x00000000 0x0000071c
  CryptoChannelPointerStatusRegister (f0042010), 0x00000000 0x00000007
  CryptoChannelCurrentDescriptorPointerRegister (f0042040), 0x00000000 0x00000000
  CryptoChannelFetchDescriptorRegister (f0042048), 0x00000000 0x00000000
  CryptoChannelDescriptorBufferRegister 0 (f0042080), 0x00000000 
 after writing to fetch register
  CryptoChannelConfigRegister (f0042008), 0x00000000 0x0000071c
  CryptoChannelPointerStatusRegister (f0042010), 0x00000002 0x00000007
  CryptoChannelCurrentDescriptorPointerRegister (f0042040), 0x00000000 0x002e9a98
  CryptoChannelFetchDescriptorRegister (f0042048), 0x00000000 0x00000000
  CryptoChannelDescriptorBufferRegister 0 (f0042080), 0x00000000 

CCPSR changes to 2 (error), but i don't know why?
Nothing else (at least nothing i can see) happens.
