Hi I upgraded my home machine to -CURRENT recently and since then (until now) I've not been able to play dvds on it. This used to work. Hardware is: atapci0: <VIA 82C686A UDMA66 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x37 6,0xffa0-0xffaf at device 7.1 on pci0 ata0: <ATA channel 0> on atapci0 ata0: [ITHREAD] ata1: <ATA channel 1> on atapci0 ata1: [ITHREAD] ad0: 76319MB <WDC WD800JB-00JJC0 05.01C05> at ata0-master UDMA66 acd0: DMA limited to UDMA33, device found non-ATA66 cable acd0: DVDR <HP DVD Writer 635d/JPS3> at ata1-master UDMA33 acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 cd0 at ata1 bus 0 target 0 lun 0 cd0: <HP DVD Writer 635d JPS3> Removable CD-ROM SCSI-0 device cd0: 33.000MB/s transfers cd0: cd present [2278670 x 2048 byte records] It's lying about the cable - it is a ATA66 cable, perhaps the port on the motherboard is not UDMA-66 capable. I get the following error: acd0: FAILURE - REPORT_KEY ILLEGAL REQUEST asc=0x6f ascq=0x04 acd0: FAILURE - REPORT_KEY ILLEGAL REQUEST asc=0x2c ascq=0x00 ata1: FAILURE - non aligned DMA transfer attempted acd0: setting up DMA failed If I set the mode on acd0 to WDMA2, then it works fine.
