Hi,
I reported this also for 2.6.20 kernel.
new libata with controller nVidia CK804 initializes the disk in DMA/33,
with with 2.6.19.5 and previous the disk is correctly inizialized in 
DMA/100.
Tha cable is OK, and with older kernels the disks runs without troubles.

The sistem has two sata disks on nvidia CK804 controllers, and then a disk 
as primary master, and a dvd writer (DMA/33) as secondary master)

here is lspci -vxxx

Cable detection on CK804 is basically broken at the moment.  It should
be fixed with Alan's acpi cable detection magic soon (maybe 2.6.21).

Thanks.

I have the pieces that fix all this, but not yet integrated into the main
tree. With 2.6.21rc3 you have 80 wire cables you may find that simply
hacking the driver to set ATA_CBL_PATA80 is sufficient, but maybe not.
