I'm trying to transfer my DVD collection to my media server, but whenever I run vobcopy, /var/log/messages gets spammed with: acd0: FAILURE - non aligned DMA transfer attempted acd0: setting up DMA failed I added a bit more information to the first message to see if I could figure out what was actually going on. request->data was 0xd40e0c37, ch->dma.alignment was 2, and request->bytecount was 2048. My first guess was that my DVD drive was starting to flake out, so I bought another one in the hopes that it would fix it, but that wasn't the problem. The drives that I've tried are: DVDR at ata0-slave UDMA33 DVDR at ata6-master SATA150 The ata controllers are detected as: atapci0: port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xec00-0xec0f at device 13.0 on pci0 ata0: on atapci0 ata0: [ITHREAD] ata1: on atapci0 ata1: [ITHREAD] atapci1: port 0x9f0-0x9f7,0xbf0-0xbf3,0x970-0x977,0xb70-0xb73,0xd800-0xd80f mem 0xcfffd000-0xcfffdfff irq 20 at device 14.0 on pci0 atapci1: [ITHREAD] ata2: on atapci1 ata2: [ITHREAD] ata3: on atapci1 ata3: [ITHREAD] atapci2: port 0x9e0-0x9e7,0xbe0-0xbe3,0x960-0x967,0xb60-0xb63,0xc400-0xc40f mem 0xcfffc000-0xcfffcfff irq 21 at device 14.1 on pci0 atapci2: [ITHREAD] ata4: on atapci2 ata4: [ITHREAD] ata5: on atapci2 ata5: [ITHREAD] atapci3: port 0xc000-0xc007,0xbc00-0xbc03,0xb800-0xb807,0xb400-0xb403,0xb000-0xb00f mem 0xcfffb000-0xcfffbfff irq 20 at device 14.2 on pci0 atapci3: [ITHREAD] ata6: on atapci3 ata6: [ITHREAD] ata7: on atapci3 ata7: [ITHREAD] Setting hw.ata.ata_dma and hw.ata.atapi_dma to 0 doesn't help any. General drive usage (browsing through the contents of the DVD, watching a movie with VLC) doesn't give the DMA errors. I'm currently using 8.0-BETA3 r196774 i386. Any suggestions? Ryan
