This is a known problem - if the Intel ICH5/6 controller is used in
combined mode (SATA mapped to legacy IDE ports), DMA for PATA devices
does not work. If you reconfigure the controller in BIOS to not use the
combined mode (so that the SATA part becomes a separate PCI device), DMA
for PATA devices will work fine.
To IDE developers: Is something planned to work around this problem?
AFAIK, there are some machines where BIOS does not provide an option to
turn off the combined mode.

This is expected behavior.
This is a limitation of "combined mode". Turn off combined mode
(sometimes called 'legacy' mode) in your BIOS, if your BIOS lets you.

This limitation exists because two drivers (drivers/ide and libata) want
to use different parts of the same hardware.
Once libata can do ATAPI 100%, when we can just let libata handle both
PATA and SATA, which will enable DMA again.

Hi there,
Got similar looking problem here,
i cant change sata modes or something alike...
I get *disabling irq* message with Intel ICH 4 / SIL 3112 A rev 01
SATA Controller on Asus P4G8X Deluxe board (P4 Northwood, Intel
*granite bay* E702 Chipsets) at distros which using newer kernel than
2.6.5, manual installation of kernel >= 2.6.7 fails
(well i think udev isnt creating devices or something cause after i
did try compile the kernel on my own etc...
kernel modules found the sata controller, the devices and the
partitions, but hangsup with an *waiting for /dev/sda3 (my root disk)
to appear*)
my messages are known i think... but for completion:
(i did copied it from net this isn exactly my error
cause i dont know how to copy the error, after failed boot...)

i got that problem after a new installation of my system, before that
it worked with a 2.6.10 kernel on same system (something about 4 weeks
ago dont know settings anymore sorry...)
well im trying some different partition style layouts,
cause i just get that message with an seperate boot partition formated
with ext3,
if i set up a blank installation without that */boot* it works fine,
even with newer version's...
if u got an idea, need some logs infos etc message me :-)

That doesn't matter under SATA.

This is a totally different problem.

Thanks for your help and advices!

Note to others:
If you are brave and pull down Jeff's libata-dev tree,
then it already has ATAPI DMA working (mostly) therein.
That's what I've done on my newest ICH6M machine here,
and both the PATA HD and PATA DVD-RW are working just fine
in "combined mode" using ata_piix. After applying a bugfix
patch for ATAPI error handling (which Jeff has just posted
here today somewhere for general comments).
Cheers.

Yeah, like on my Dell Inspiron 9300.
