Public bug reported:

Binary package hint: initramfs-tools

With linux-image-2.6.24-16-generic and Panasonic CF-R1(440MX/Pentium III), 
after upgrading kernel package and initramfs-tools package in Apr. 12th, it 
fails to mount root file system in initramfs. It goes busybox shell in several 
minutes after showing 'waining root file system' message.
It works fine by the hardy's packages  in Apr. 9th(2.6.24-15-generic and 
2.6.22-14-generic).

A machine uses 440MX chipset it was recognized as hda in 7.04 and 7.10 but 
hardy recognize it as sda.
I found ata_piix and sd_mod is not loaded then couldn't find the device in 
busybox session.

After loading ata_piix/sd_mod, it can recognize hdd and I mount root filesystem 
by hand.
I can fixes initramfs image by hand such as follows:

(initramfs) modprobe ata_piix
(initramfs) modprobe sd_mod
(initramfs) mkdir /mnt;mount /dev/sda2 /mnt
(initramfs) chroot /mnt /bin/bash
[EMAIL PROTECTED]  echo ata_piix >> /etc/initramfs/modules
[EMAIL PROTECTED]  update-initramfs
[EMAIL PROTECTED]@ update-grub

then reboot, works fine.

A problem looks like a bug on a upgrade script in initramfs-tools
package or an auto detection of chipset(udev?).

versions 
initramfs-tools 0.85ubuntu36 - (updated April 10th according to changelog)
linux-image 2.6.24-16-generic, 2.6.22-14-generic, 2.6.24-15-generic
