So we've established that your controller doesn't seem to want to do DMA. You seem to be using the piix driver, correct? I do, too...
Could you post a dmesg from 2.4.27-1-686, and also try some older kernels to see if this is a regression and not a bug that has always been there? (Hint: kernel-image-2.4.26-1-686)
Behold piix.c, 2.4.27:
/* UDMA 33 capable */ case PCI_DEVICE_ID_INTEL_82371AB: <--- this is you case PCI_DEVICE_ID_INTEL_82443MX_1: case PCI_DEVICE_ID_INTEL_82451NX: case PCI_DEVICE_ID_INTEL_82801AB_1: return 1;
So it SHOULD be working.
Also attach the output from cat /proc/ide/piix.
Note, if it doesn't exist, piix refused to handle your device, which sounds like the older problem (except that it's fixed now!)
I've not sent this to BTS. If you think it should be there, feel free.
I'm probably as puzzled about this as you. What's the difference between these?

I used to run 2.4 kernels on Dolphin, never noticed a problem (except lack of RAM). It's now running 2.6.7-1-686, the same kernel that's not detecting the ATA drive on ns.

_That_ is about what I expect, and I've changed my mind about not sending this to the bts.
Here's what I did:
lspci
find /lib/modules/$(uname -r) -name piix.o
ls /lib/modules/2.4.27-1-686/kernel/drivers/ide/pci/piix.o
lsmod
lsmod
rmmod ide-cd
rmmod ide-disk ide-detect ide-cd
lsmod
rmmod ide-core cdrom
modprobe piix
dmesg | tail
hdparm -t /dev/hda
modprobe ide-disk
hdparm -t /dev/hda
lsmod
modprobe ide-detect
dmesg | less
hdparm -t /dev/hda
hdparm -t /dev/hda{,,}
hdparm /dev/hdaThe drive didn't detect until I loaded ide-detect. I guess that's logical, but something should pull something in....

For completeness I'd like to know what I did wrong. However, if I can get a working 2.6 kernel I'll be happier.
