I am having trouble enabling DMA on a recently installed motherboard. (Intel D845GBVL - 845g chipset). I am running a fresh RedHat7.3 install and have tried the stock RH kernel, and I'm up to 2.4.19-pre9. I have a CD burner and DVD drive attached which operated with DMA on an older 845 mobo. If I run hdparm -d1 /dev/hd(a or c), I now get:
HDIO_SET_DMA failed: Operation not permitted
Here is a snippet from dmesg:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086, DID=24cb PCI: Device 00:1f.1 not available because of resource collisions PCI_IDE: (ide_setup_pci_device:) Could not enable device.
Here is some lspci
00:00.0 Host bridge: Intel Corp.: Unknown device 2560 (rev 01) 00:01.0 PCI bridge: Intel Corp.: Unknown device 2561 (rev 01) 00:1d.0 USB Controller: Intel Corp.: Unknown device 24c2 (rev 01) 00:1d.1 USB Controller: Intel Corp.: Unknown device 24c4 (rev 01) 00:1d.2 USB Controller: Intel Corp.: Unknown device 24c7 (rev 01) 00:1e.0 PCI bridge: Intel Corp. 82801BA/CA PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corp.: Unknown device 24c0 (rev 01) 00:1f.1 IDE interface: Intel Corp.: Unknown device 24cb (rev 01)
I followed some recent threads, and tried fixes to similiar problems but I'm still locked out.
Aside from this glitch everything else seems to run fine. Could someone give my a hand? Am I missing something simple, is my bios borked, or do I need a patch to support the newer chipset?
Thanks,
Tony
