Does the latest CVS version work with an IDE controller in DMA mode? I have an NEC VR5432 based system working with the IDE controller, but it crashes when used in dma mode. I've tracked it down to the following code called from ide_build_sglist(): - blk_rq_map_sg() is called to build a list of blocks to be transferred. It sets address = NULL for every entry (other fields like "page" are set to valid values). - dma_cache_wback_inv(addr, size) is called for each block entry. This routine crashes because the address parameter is always set to zero when the routine is called. I see that this is part of the new bio code recently added. Should I expect this code to work, or is it not yet working for the mips platform? Thanks. Gerald
