Thank you. Hmm, you are not getting the DMA resource, or the PCI config registers are not responding as they should. To get more info you should instrument the code in ata-pci.c around lines 178-190 to see what it is that rejects the DMA resource. Something changes in the resources/PCI config that is sent to the ATA driver so that it either cant get at the I/O ports for DMA or so that the PCI config regs wont allow busmastering to be enabled.. Wether this is in ACPI or the PCI code I cant tell without more info from doing the above instrumenting.. -SørenReceived on Wed Aug 11 2004 - 05:19:12 UTC
