SubjectBus Mastering DMA , the Triton I chipset ,and the 2.2.5 kernel
Date
I have the Intel 82371FB PIIX ISA-PCI bridge with two ide ports. The driver has
autodma configured. When attempting to set BM-DMA with hdparm, all of the disks
are bus master capable, I get the error:
HDIO_SET_DMA failed: Operation not permitted.
Under 2.0.36 BM-DMA was enabled. Is this a bug? Is there a known work-around?
Is there a patch which allows triton.c from the 2.0. series to be used like
some of the specialized drivers.


David
