Nearly 100% CPU Usage from processes called dma0chan0 dma0chan1 dma0chan2 dma0chan3

I never started these processes but they are from a custom based bootable Linux I've made and I've never seen this behavior on other machines or even with the same machine using different kernels.  These processes seemed to spawn on their own and I have no idea why and even worse why the CPU usage is so high?

Here's the output from top:

  907 extaudit  30  10     0    0    0 R 90.7  0.0  16:26.16 dma0chan0-copy0                                    
  908 extaudit  30  10     0    0    0 R 90.7  0.0  16:25.78 dma0chan1-copy0                                    
  909 extaudit  30  10     0    0    0 R 90.7  0.0  16:24.45 dma0chan2-copy0
