Hi all, I updated my G3 iMac DV with CURRENT src and built a generic kernel. And now my system hangs at boot: Feb 14 16:35:58 imacb kernel: ad0: 78167MB <Maxtor 6Y080P0 YAR41BW0> at ata0-master UDMA66 Feb 14 16:35:58 imacb kernel: acd0: DVDR <MATSHITADVD-ROM SR-8184/AA32> at ata0-slave UDMA33 -- hanger --, no reaction, nothing. Last time I played with this machine was back in October. I had a running system with Nathan's ata patch. I could not figure any change in this area causing the hang. I read through the list and also tried to disable dma with hw.ata.ata_dma=0 and hw.ata.atapi_dma=0 at boot time. No success, hangs. The log tells about PIO4 iso. UDMAxx. Right now I can only boot with the kernel from last October. The strange thing is, I managed to build a kernel with GENERIC which was able to write down the bootlog to disk. So, I assume it somehow did work to mount the root disk. Unfortunately this is not reproducable. Here the relevant snippets from the bootlog: Feb 14 16:35:58 imacb kernel: ata0: <Apple MacIO Ultra ATA Controller> mem 0x1f000-0x1ffff,0x8a00-0x8aff irq 19,11 on macio0 Feb 14 16:35:58 imacb kernel: ata0: [ITHREAD] Feb 14 16:35:58 imacb kernel: ata1: <Apple MacIO ATA Controller> mem 0x20000-0x20fff,0x8b00-0x8bff irq 20,12 on macio0 Feb 14 16:35:58 imacb kernel: ata1: [ITHREAD] Feb 14 16:35:58 imacb kernel: ata2: <Apple MacIO ATA Controller> mem 0x21000-0x21fff,0x8c00-0x8cff irq 21,13 on macio0 Feb 14 16:35:58 imacb kernel: ata2: [ITHREAD] Anyone an idea who to debug? I have the OF properties at hand, of the devices: disk: /pci@f2000000/mac-io@17/ata-4@1f000 dvd/cd:/pci@f2000000/mac-io@17/ata-3@20000 Would they be a help? TIA, Andreas
