I've no idea whether a similar 'quick-fix' to that given for FreeBSD 4.X to /sys/dev/ata/ata-dma.c would work with the 5.5-S and 6.1-R code I have here, noting that the alignment is now specified in bytes rather than the earlier bytes-1, so '4' is presumably the value needed for dword alignment. Hmm, ok, trying to dig a little deeper .. rev 1.118 notes say: Add support for a the National Geode SC1100. Thanks to Soekris engineering for sponsoring a Soekris 4801 to make this support. but I couldn't find anywhere in 1.118 or in later versions up to 1.147 (RELENG_7, HEAD) that does anything other than 'ch->dma->alignment = 2;' (Not that me not finding it means much :) I also noticed at 1.137.2.2: Add support for using DMA on dump, greatly speeds up the dump process. Copying Soren in case he may have a bead on this, but it hardly seems any impediment to preparation or building for it when the box arrives. Cheers, Ianhelp
