I had DMA problems with ftape starting with kernel 2.0.0. The solution
was to upgrade to ftape-2.10 (or newer?) and run the program called
swapout that came with ftape before loading the ftape module manually
or by kerneld.
It appears dmaalloc() must have sufficient non-fragment memory in order to
succeed. Swapout helps by defragmenting memory by allocating a five Meg
chunk and then freeing it.
