I'm getting weird DMA errors on my Fedora Core 5 computer. The motherboard is an ASRock P4VM800 with 512MB DDR Celeron 2533 MHz Model 4 hard drive is a Hitachi 7K80 7200 rpm parallel-ATA 80 Gig. Fedora is installed on /dev/hda7 9.4 Gig partition ext3 The DMA error message shows up during big file, or multiple file, copying from one directory to another, and during bootup. dmesg shows this message: cd ..hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } hda: dma_intr: error=0x84 { DriverStatus Error BadCCR } ide: failed opcode was: unknown Sometimes the error message shows up at one point in the boot process, sometimes in another. During really big copies, the DMA error message is quite frequent. I also have XP, 98SE, and Slackware on the machine but so far none of them have this error, or maybe they're not telling. Can anyone tell me how to deal with this problem?
