Hi Albert.
Yes, it's normal that it fails that way on your machine.
It just says, that your machine/CPU needs a "cache-writeback"
command by the cpu before any other chips may access that
area of memory directly via dma.
In other words, your machine isn't cache-coherent and this
will be handled automatically by the driver.
Btw, harmony (sound), lasi_82596 (LAN) and other drivers have
the same problem, but mostly don't inform you about that.
Greetings,
Helge
