Well, It has nothing to do with DMA...

So, do you mean that single_cmd _always_ appears even before the
suspend?  Then it's not the problem of suspend-to-RAM but rather it's
a pure luck that you can use that device.  The single_cmd is a last
but horrible resort for the systems that can't communicate with codec
chips properly.

suspend-to-disk.
