For those who may have missed my other message, it looks like all of my problems were related to a PCI-based SATA controller which was added by the store that built my machine. This card was added even though I had selected a motherboard with on-board SATA. The problem controller was a: and it has been causing me enough problems that I couldn't get through a buildworld to even try the suggested patch. I have now switched to the on-board: and so far I have not seen any more of these WRITE_DMA messages. None. And I have been pounding the disk pretty hard with a variety of work for a few hours now. So, now there is no point in me adding the patch, because I no longer see the message! It would still be nice if FreeBSD would react better to whatever problems this card causes. I still have this stupid card, and I would be happy to mail it off to anyone who might want to debug the problems with it. And if we *can't* fix it, then maybe we should just remove support for it. I have had to rebuild my freebsd partitions several times now due to these problems, and certainly that wasn't much fun. Although I guess my problems might also be partially due to the Western Digital drive I was using, when it is used in combination with this card. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
