I have no box here to test this - my laptop won't help.
On my NV3 board with a Samsung SP1634N Harddisk I wrongly got
"drive side 80-wire cable detection failed" with the current kernel.
Does the drive cable detect correctly on a non Nvidia chipset ?
But I did another test:
I replaced the 80-wire cable with a 40-wire cable. Then the BIOS warns
about "no 80-wire cable connected". The kernel boot and seems to enable
UDMA100 which leads to some BadCRC errors. After that the drive is in
udma3-mode(hdparm) IIRC but not in udma5, as when using the right cable.
Maybe it's not that clever to add the drive to the ivb_list?
As far as I understood it, pata_acpi should fix the problem, but I'm not
sure on the required configuration. Do I have to disable the normal
IDE-support? How 'experimental' is the PATA support?
