Hi,
I've tried this patch set (with the typo-corrected part 4) on my ASUS WL-500gP v2 MIPSEL via a backport to 2.6.31.9, but all I get is a small blip of the sound I wanted to play, and then the system is fubar (I believe just the same thing as what happened without having this patch applied).
As I mentioned in the previous followup, if your device is a USB-audio, the patch doesn't help because it's for devices with buffers using dma_alloc_coherent(). For USB-audio, it uses vmalloc for an intermediate buffer. Maybe this should be changed to dma_*() stuff for such architectures.
Nevertheless, I don't know whether the crash is related with the audio part...
