The call[2] in line 608 is:
  WriteDataPages (m_trans, nodePtrList, 0, cluster);
with '0' as the third parameter, the cluster offset
but the debugger prints the value in the called function as 'Offset = 
16776575'
-> this is not what we expect here :-)
The kernel crashes as the the array tbd00_NodePtrList &pNodes is 
defined for a maximum
of 64 elements.
