I'm having trouble with DMA on my disks. I've used DMA on these IDE disks before, but for some reason I can't now. When I run "hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda", for example, it all sets fine except DMA. For that it says, "HDIO_SET_DMA failed: Operation not permitted". I know I've used DMA on these two drives before. I checked my kernel config and, sure enough, I have DMA enabled:
linux # zcat /proc/config.gz |grep DMA CONFIG_GENERIC_ISA_DMA=y CONFIG_ISA_DMA_API=y CONFIG_BLK_DEV_IDEDMA_PCI=y # CONFIG_BLK_DEV_IDEDMA_FORCED is not set CONFIG_IDEDMA_PCI_AUTO=y # CONFIG_IDEDMA_ONLYDISK is not set CONFIG_BLK_DEV_IDEDMA=y # CONFIG_IDEDMA_IVB is not set CONFIG_IDEDMA_AUTO=y What else can I check? -todd -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
