I already tried pata_it821x and it failed to recognize the second
harddisk hdf. I use the controller only for additional harddrives,
no RAID, no cd-rom.

Logs from that would be most helpful as I am maintaining the
pata_it821x driver.


Okay, I removed the IDE one and tried your libata driver again.

What I maybe just did wrong on my first try, was loading it without any
parameters, as:
pata_it821x: Unknown parameter `it8212.noraid'
pata_it821x: Unknown parameter `it8212_noraid'
Loading without any parameters on this kernel resulted in:
pata_it821x: controller in smart mode.

Now I tried with "noraid=1", and now all seems to be working fine.

Thanks very much!
