In the light of recent DMA-related problem reports with SanDisk (and
other) CF cards on net4801 and even generic PCs, I'm wondering if we
should just turn off DMA completely in all images? The read/write
activity (loading the image during boot and reading/writing the
configuration) is so low that it shouldn't make any noticeable
difference, and I've never heard that DMA ever worked better than PIO
in terms of reliability (and performance doesn't count much here).

What are your thoughts?
