Hi,

I'm trying to use dmatest driver on MPC8536DS running linux 2.6.31-rc5. The loading of driver fails, as it is unable to allocate DMA channel. Is this driver supposed to work with FSL DMA engine ?

Thanks.

Felix.

I should have disabled "TCP receive copy offload" DMA client. dmatest works now as expected. Sorry for the noise.
