Hi, I have been trying to install yesterday's 4.0 snap on a no-name brand motherboard with the VIA chipset, but I'm running in some problems. I suspect there is a problem with the DMA. The error I'm getting when the disk is newfs'ed is a repeating: ad0: WRITE command timeout - resetting ata0: resetting devices .. done ad0: WRITE command timeout - resetting ata0: resetting devices .. done ... It seems that it is just going on and on. Shouldn't it back down to non DMA mode after a while? Is there a way to disable the DMA on the install floppies? Part of the probe looks like this: (written down by hand) atapci0: <VIA 82C586 ATA33 controller> port 0xe000 - 0xe00f at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ... ad0: 6204MB <ST36531A> [13446/15/63] at ata0-master using UDMA33 John -- John Hay -- John.Hay@mikom.csir.co.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
