no, but at latest kernel 2.6.19-rc1 use the same tree as you said, and
it also can worked
I see. It's irrelevant anyway.
And, one more thing to try. The following patch should fix your
problem. It's against v2.6.18.
while applied the patch, error info gone :)
A question: if the status register return 0xFF means the device not exist?
why not use ata_devchk()?
Many SATA controllers emulate TF registers and pass devchk even when no
device is attached. I don't know whether the two conditions can happen
together - 0xFF status is usually seen on PATA. Anyways, it's more
reliable to test 0xFF. Also, that's what driver/ide has been doing for
a long long time and we don't want to deviate from it if possible.
