I'm having problems enabling DMA for my PATA HD.
hdparm -d1 /dev/hdb reports: HDIO_SET_DMA failed: Operation not permitted
Of course, I'm super user. Nothing is printed in dmesg.
I'm on linux-2.6.16 and motherboard is Fujitsu Siemens D1561 with an ICH5. I also have a SATA hd in the computer and this only happens when the SATA hd is there. If I remove the SATA HD, then I can enable DMA for the PATA hd.
Both the SATA and the PATA are very new.
# zcat /proc/config.gz |grep -i 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 # CONFIG_SCSI_PDC_ADMA is not set
Any pointers as to what I can try?
