Hi,
since upgrading to kernel 2.6.20 my pata disk, using new pata driver, is
initialized maximum in DMA33 mode, as you can see from:

I have other 2 sata disks on this system, and I have no problems with
them. I Wonder if this is due to some controller/disk problem triggered
just by 2.6.20 kernel (I saw there are a lot of changes into eh code),
while 2.6.19.X and previous sees everything OK.
This system is an Athlon64 X2 3800+ with an nvidia2 IDE controller

Send patches. We also probably want to change speed straight from
UDMAlots to UDMA33 if the cable is CBL_UNK so that we can rapidly recover
in the cases where the controller says "I'm crap I don't really know" (eg
ATI and Nvidia without ACPI)

Well, the cable is OK, of course I checked.

As an aside to this sort of problem, shouldn't we print some kind of
loud message in dmesg when we force a high-UDMA-capable device down to
UDMA33 due to a 40-wire cable detection? In the case where it truly is a
40-wire cable the user may want to know that and replace the cable, if
it isn't it gives more of a hint of why the drive isn't running at full
speed..

I did the test you asked and yes, it is consistently booting at DMA33 with
2.6.20 and DMA100 with 2.6.19.3 (20 reboots, 10 2.6.20 and 10 2.6.19 in
sparse order).
I am compiling a 2.6.20 kernel with older pata_amd.c driver and will let
you know. seeing the diff I do exspect it to compile cleanly.

Firstly can you see if its consistently the case that booting 2.6.20
gives UDMA33 and 2.6.19 UDMA100 over a few reboots. If it is please drop
the 2.6.19 drivers/ata/pamd_amd into 2.6.20 and try that.

I boot 2.6.20 also on a pentium4 with intel 82801EB/ER (ICH5/ICH5R) IDE
Controller and the same pata disk.
On this controller the disk runs in DMA100 as it should, so I'm prone to
think it is a pata_amd.c driver trouble. Should try downgrading this
driver from version 0.2.7 to version 0.2.4?
I looked at the diff, but I do not see why the new "static int
amd_reinit_one(struct pci_dev *pdev)" , that has inside a clear
a if (pdev->vendor == PCI_VENDOR_ID_AMD), should have some impact on a
nvidia controller.
suggestions?

Hi,
since upgrading to kernel 2.6.20 my pata disk, using new pata driver, is
initialized maximum in DMA33 mode (and obviously performances drop
consequently), as you can see from:

I have other 2 sata disks on this system, and I have no problems with
them. I Wonder if this is due to some controller/disk problem triggered
just by 2.6.20 kernel (I saw there are a lot of changes into eh code),
while 2.6.19.X and previous sees everything OK.
Also forf the sata disks, in fact, I see this "doesn't support DPO or FUA"
warning, but I have to admit I do not know which features it is referred to.
This system is an Athlon64 X2 3800+ with an nvidia2 IDE controller
