Oh... I thought you were using libata drivers because you mentioned
pata_it821x on the subject. The IDE driver supports 'hdparm -d 1' fine.
I wonder why that's not working. Also, the driver is configuring your
disk to PIO0.
Cc'ing Alan and Bartlomiej. Guys, is this the smart mode problem? Do
ide and libata have this fixed in 2.6.24-rc?
Thanks.
