I _knew_ I enabled the DMA, but it seems that is switches off when I start the transfer: hdc: DMA disabled hdc: ide_intr: huh? expected NULL handler on exit hdc: ATAPI reset complete ISO 9660 Extensions: RRIP_1991A VFS: busy inodes on changed media. This is on hdc, which is the DVD. Harddisk has DMA on.
