It just started happening today, and has only happened a couple of times. The drive appears to still be working. I get a little paranoid about this system, as it's in nothern CA and I'm in southern CA, about 500 miles away. Since I'm hosting a lot of virtual web domains on this machine, it's super crucial that it run reliably. I just put this box on line last week, replacing a Pentium 150 with 128 MB RAM running FreeBSD 3.0-SNAP-9808something. I don't remember whether the BIOS supports DMA mode - next time I'm in NorCal working on the beasty I'll check it out. It sounds like I need to keep watching the logs, and if I see this message show up more often I'll get worried about it; if not, then I'll remain cool and trust that it's not about to fall over. Thanks for the explanation. It helps calm my nerves a bunch.
