My ppc based Mac G4 (Digital Audio) boots and functions properly 24x7 in its role as fileserver in my home network. The machine has two IDE hard drives (wd0(wdc0:0:0) and wd1(wdc0:0:1)) attached. It boots from wd0 and mounts wd0a as / with wd0b as swap. These partitions are specified by DUID in /etc/fstab. I have successfully installed a supported SATA PCI card which adds 2 SATA ports and one IDE port to this machine and it continues to function. When I add one drive to the SATA controller, the new drive is identified as wd0. The root drive is identified then as wd1. Though the root drive is specified by DUID in /etc/fstab the kernel reports it is attempting mount root as wd0a with wd0b as swap before failing and dropping to ddb> What should I do next to troubleshoot and solve this problem? I'll give detail below in sequential order of what happened: 1. The machine first was installed and operated with no additional drives: Original dmesg with no cards: http://justinhaynes.com/wiki/index.php?title=Power_Mac_G4_Digital_Audio_dmesgs#nocards $ cat /etc/fstab 009339b689499a74.b none swap sw 009339b689499a74.a / ffs rw 1 1 009339b689499a74.l /home ffs rw,nodev,nosuid 1 2 009339b689499a74.d /tmp ffs rw,nodev,nosuid 1 2 009339b689499a74.f /usr ffs rw,nodev 1 2 009339b689499a74.g /usr/X11R6 ffs rw,nodev 1 2 009339b689499a74.h /usr/local ffs rw,nodev 1 2 009339b689499a74.k /usr/obj ffs rw,nodev,nosuid 1 2 009339b689499a74.j /usr/src ffs rw,nodev,nosuid 1 2 009339b689499a74.e /var ffs rw,nodev,nosuid 1 2 cf2accc79e4b7bfc.i /home/bs ffs rw,nodev,nosuid 1 2 2. A card was added, which did not prevent it from booting and operating normally: $ diff nocards.dmesg rosewill_rc-215.dmesg 27a28,29 > pciide0 at pci1 dev 20 function 0 "VIA VT6421 SATA" rev 0x50: DMA > pciide0: using irq 54 for native-PCI interrupt 3. I attached one ~1 terrabyte drive to pciide0 mentioned above, booted up and got the error I described. The last few lines of the dmesg and the first few of the ddb> output appear here. I do not have a way to capture output from the serial console at this time, so I typed out the lines. The previous lines are identical to the original dmesg + the extra card: http://justinhaynes.com/wiki/index.php?title=Power_Mac_G4_Digital_Audio_dmesgs#dmesg_with_rosewill_rc-215_VIA_VT6421_SATA 4. I booted up with bsd.rd, used fdisk to create an OpenBSD partition taking all of the last partition, partition #3. I then created a disklabel with only one slice, i, and ran a newfs. I did generate a DUID on this disk. I confirmed it was mountable and that files could be written to and read from the drive. 5. I rebooted the machine and got the same result as in #3. Thanks!
