Bug Description

My motherboard's (ASRock P45XE) PATA controller only works when i use the all_generic_ide option. At least it did up to 2.6.28-4.6. Since updating to 2.6.28-4.9 this workaround stopped working.

Let me know if i can provide further information.
Thank you.

My PATA IDE device seems to only be 'supported' by the pata_acpi and ata_generic drivers. pata_acpi loads but doesn't detect the device so i need a way to load ata_generic instead.

In the 2.6.28-4.6 kernel the IDE drivers were modules, 4.9 has them compiled into the kernel and i couldn't find a way to disable pata_acpi.

This affects me too. My old box doesn't work with libata, it gives revalidation errors and fails to boot, therefore i build my own amd74xx module and blacklist the libata ones, unfortunately this no longer works.

It seems that ata_generic.ko is missing! It has not been built. Please correct it, since it breaks some older hardware.

It affects me too!

Temporary workaround: install linux-image-386, there is ata_generic.ko compiled with it, so it will work.
