[SOLVED] Booting from Asus U3S6 SATA Controller fails

Since the SATA controllers on my mainboard stopped working yesterday, I bought a Asus U3S6 Controller in the hope to work around the problem in this way. The drive is detected by the BIOS and GRUB is invoked correctly. However, when I try to load the kernel, I get following message:

Waiting 10 seconds for device /dev/sdb3 ...
ERROR: Unable to find root device '/dev/sdb3'.
You are being dropped to a recovery shell

In the recovery shell I cannot find any disk device under /dev/. Is this kind of booting supposed to work? When is the PCI controller actually detected and activated by the kernel?

Any help appreciated!

Re: [SOLVED] Booting from Asus U3S6 SATA Controller fails

I solved the problem.

I used used the chroot guide to modify my environment:

I had to add ahci to the list of modules in /etc/mkinitcpio.conf and rebuild it with

mkinitcpio -p linux

This will then load the AHCI module at boot time and enable the SATA devices.
