Comment 29 for bug 106864

I have followed Ben's advice, using modprobe piix, and got Feisty installed on my parallels guest (in a mac mini). After rebooting to the installed system (again using modprobe piix) I put piix into the initramfs modules file and ran the update. On the next reboot I am still prompted by busybox and still have to do modprobe piix to boot. The entry is in the modules file so I suspect initramfs is not using the modules file at the point it prompts.
This problem needs an urgent fix since it seems to affect quite a number of different systems.
On the face of it the kernel was built with piix as a module, rather than built-in.
