Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Tue, 18 Jan 2000 19:03:02 +0000 From: Brian Somers Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi, I don't know if you'd class this as a bug report or more as an observation. I have a machine with the following: ata-pci0: port 0xf000-0xf00f at device 15.0 on pci0 ata-pci0: Busmastering DMA supported ata0 at 0x01f0 irq 14 on ata-pci0 ata1 at 0x0170 irq 15 on ata-pci0 [.....] ad0: ATA-0 disk at ata0 as master ad0: 1623MB (3324384 sectors), 3298 cyls, 16 heads, 63 S/T, 512 B/S ad0: 16 secs/int, 1 depth queue, WDMA2 ad1: ATA-4 disk at ata1 as master ad1: 7339MB (15032115 sectors), 15907 cyls, 15 heads, 63 S/T, 512 B/S ad1: 16 secs/int, 1 depth queue, UDMA33 ad2: ATA-4 disk at ata1 as slave ad2: 26063MB (53377152 sectors), 52953 cyls, 16 heads, 63 S/T, 512 B/S ad2: 16 secs/int, 1 depth queue, UDMA33 Note that ad0 is on a controller of its own, and ad[12] are on the second controller. If I put the second (7Gb) disk on the first controller as slave, I can't get the machine to boot. The wd driver works ok, but ad, although coming up in the ``?'' list in vfs_mountroot_ask(), won't boot... I get error 6 when I try ufs:/dev/rad0s1a at the prompt. This has stopped me going to the ata driver on this machine for a long time :-/ Moving the two UDMA disks to a controller of their own has solved the problem....
