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.
ACPI: PCI Interrupt 0000:00:09.0[A] -> GSI 17 (level, low) -> IRQ 18
scsi3 : pata_it821x
scsi4 : pata_it821x
ata3: PATA max MWDMA2 cmd 0x0001ec00 ctl 0x0001e802 bmdma 0x0001dc00
irq 0 
ata4: PATA max MWDMA2 cmd 0x0001e400 ctl 0x0001e002 bmdma 0x0001dc08
irq 0 
ata3: SRST failed (errno=-16)
ata3: SRST failed (errno=-16)
ata3: SRST failed (errno=-16)
ata3: SRST failed (errno=-16)
ata3: reset failed, giving up
---------------------------

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

Thanks very much!
Thomas
