Comment 30 for bug 47768

I've exactly the same problem as Martyn Russell.

I've upgraded my distro to Feisty, and now when i try to reboot i get :

Loading essential drivers ... OK
Running /scripts/init-premount... OK
Mounting root file system ...
Running /scripts/local-top ... OK
Waiting for root file system ...

And nothing more...
If i boot with the old kernel 2.6.17-10 and initrd 2.6.17-10 it works well and my new feisty boot.

I think there's a problem with the new initrd and sata controllers...

How could help you to debug that?
