While not testing this idea on that exact board I did try that on a second system with VIA chipset (82C693 with 82C596A IDE) with no obvious improvements. On this system even fallings back to hw.ata.ata_dma=0 didn't help & in fact made things worse. > I've seen problems that were specific to solid-state flash that happened > only on the primary, never on the secondary...it's possible you're running > into a variation on that theme. I solve the problem on the Aplus board by turining off hw.ata.ata_dma in /etc/loader.conf. While a bit slower the resulting system works which is the main issue at this time. Thanks, Tony
