I'm forwarding my mail to lkml also.

As addition to the information, mobo is ASUS A7M266 and Promise BIOS
version is 2.20.0.12.

Hello,

Is it normal to have pdc202xx driver to enable only UDMA33 on Ultra133
TX2 (PDC20269)? Disk is new 60GB Seagate Barracuda. U133TX2's BIOS says
it has enabled UDMA5.

Driver is: ide-2.4.19-p7.all.convert.10.patch.bz2

Here's some info from dmesg:

PDC20269: chipset revision 2
PDC20269: not 100%% native mode: will probe irqs later
    ide2: BM-DMA at 0x5800-0x5807, BIOS settings: hde:pio, hdf:pio

hde: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=116301/16/63,

/proc/pci/ide/pdc202xx says only (nothing else):

                                PDC20269 TX2 Chipset.

try using hdparm to fix this, some distributions do a better
job than others setting up hardware, and udma6 being so new
it's not unlikely that your dist simply can't take this into 
account.  I use an asusa7v266-e and have had no harddrive controller
issues in ata-100, grab the latest hdparm, and the latest kernel (ensuring
it supports udma mode 6, and compile both.

This is a bug in the driver. You need to boot with 'ide0=ata66'
(0 being the channel number) to be able to switch to udma3+ modes.
