I would say that this has something to do with the DMA support, but since Neptune's IDE controller isn't DMA capable and PCI, that doesn't follow. Chances are that there's a not-quite-bad spot on your drive -- does it always seem to happen in the same place on the disk? <soapbox> I have no love lost for Neptune boards; we have two of them at work, and it's like trying to work with a 486 board with an OverDrive chip on it. I'm also wary of Intel boards in general, since they tend to think they're smarter than you. </soapbox> -- +--------------------------------------------------------------------+ | Lee Cremeans -- Manassas, VA, USA (WakkyMouse on DALnet and WTnet)| | lcremean@tidalwave.net| http://st-lcremean.tidalwave.net/~lee | To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
