1 of 3 sata2 hdd's isn't detected on FC6 (G965 chipset)

[alc0h0lic]

Hi,

I'm having problems with my fresh install of FC6. I have a Intel DG965SS mainboard with ICH8 controller. One of my harddisks just isn't detected by the fedora kernel. In Windows Vista all 3 work.

I configured the hdd's in ACPI and in IDE mode, but still just 2 are detected by the kernel and the setup. Because this chipset is quite new, I haven't got the chance to test other distros.

I'm running the latest 2.6.18-1.2798 kernel.

If anyone has an idea what's going on, then please anwer
