disk device does not exist when booting Feisty herd 4 on GA-965GM-S2

[Marc Tardif]

After successfully installing Feisty herd 4 on a Gigabyte GA-965GM-S2 motherboard, the Ubuntu splash screen appears but then disappears with the following error message on a black background:

Check root= bootarg cat /proc/cmdline
or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/disk/by-uuid/2a7df3ea-8da1-4c7a-843a-e26d79198272 does not exist. Dropping to a shell!

The boot process then provides an initramfs prompt. There, I tried to ls /dev/disk to check if the uuid might be wrong, but the directory doesn't exist.

So, I then tried booting without the quiet and splash kernel options. I noticed a stack trace which starts with the following line:

Modules linked in: ohci1394 ieee1394 ehci_hcd generic uhci_hcd usbcore thermal processor fan fbcon tileblit font bitblit softcursor vesafb capability commoncap

And the stack trace ends with the following lines:

udevd-event[2017]: run_program: '/sbin/modprobe' abnormal exit <6>usb 5-1: new low speed USB device using uchci_hcd and address 2
usb 5-1: configuration #1 chosen from 1 choice
usb 5-2: new low speed USB device using uhci_hcd and address 3
usb 5-2: configuration #1 chosen from 1 choice

I'm not sure if this stack trace is related to the disk device which is reported not to exist, but I thought I would provide this information anyhow.

This seems similar to bug 84964.

I am seeing the exact same problem on Feisty Fawn, kernel version 2.6.20-14. I would post my lspci but I cannot boot and don't have a LiveCD handy right now.

I am seeing the exact same problem on Feisty Fawn, kernel version 2.6.20-14 too. (After the update of 11/4/2007 (but i'm not really sure of the date)).
With the same uuid I can boot with the old kernel (I upgrade from edgy) 2.6.17-10-generic (2.6.17-11-generic don't go).

I think I have the same sort of problem. When I upgraded from 6.10 one of my disks went missing. There is only one device recognised on a SCSI bus (Sudo SCSI) controller the other device is missing.

 There are two IDE ports each with a drive only sda is visible the other is missing.
The drive exists because I can see it in windows and it was there before I upgraded.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
