FreeBSD 6.2 recognized all HDs as ultraDMA 100. Fine. Then a bought a ASUS p5vd2-x, 1G ram, Gforce 7200 video(pci-e), pentium D 940 Dual core and kept the same drives. After tuning and recompiling the kernel a couple times, I got almost everything working great ! SMP, acpi, network, you name it, EXCEPT ultraDMA. if I leave: hw.ata.atapi_dma: 1 hw.ata.ata_dma: 1 FreeBSD reports them (all) at ultraDMA 33. The system boots ok but after 7 or 10 minutes (even if doing nothing), I start geting messages from g_vfs_xxxx(); WRITE DMAERROR that can come from any of the drives until the system becomes unstable and ends up rebooting itself. if I leave: hw.ata.atapi_dma: 0 hw.ata.ata_dma: 0 The HDs get down to PIO 4 and the system works fine but at an incredible performance cost. Finacial issues force me to make this work instead of buying more stuff. Thanks for any suggestions, -- ********************************************************** //| //| Mario Lobo // |// | http://www.ipad.com.br // // ||||||| FreeBSD since 2.2.8 - 100% Rwindows-free **********************************************************
