How very odd and disappointing. So a CF card might advertise DMA on its label and feature set, and show DMA modes in hdparm's info dump, but break when actually using DMA modes? Do you know of any specific CF cards which *do* support DMA? - Josh Triplett _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
