Change it to DMA_BIT_MASK(32) instead, which is a more > sensible value anyway. Isn't 32 the default value usually? Not sure a about PCI devices, though. It also made sense to set it to 31, since the comment talks about a workaround for > 2GB ram (and 2GB ~~ 31 bits). Or, is the workaround really only needed in the coherent mask and is that the reason why you didn't change the coherent dma mask to 32? If this is so, wouldn't it make sense to only set the coherent dma mask and leave the dma mask at whatever default (just guessing here...). Gr.
