Having read this thread it seems I have fallen foul of the same problem. My laptop has Intel ICH4. I ran the updates (including the kernel) having installed Mint Casandra KDE alongside the XFCE version and Win XP.

A lot of very strange things have been happening with the KDE edition and I cannot do a straight boot of XFCE.

This is content of var/log/fsck/checkfs of the XFCE system.

I will reboot with the previous kernel.

Do I need to do anything else to restore things to good health?

How do I uninstall the latest kernel in the 2 systems? Sorry to ask but I'm still feeling my way with Linux.

Thanks

at boot hit escape so you can see the boot menu.
you will now see the new kernel and the old one below it (third one).
boot off the old kernel.

open synaptic and look/search for the new kernel and choose to uninstall it.
apply.

now when you boot you will only have the old kernel.

:D

Now where was i going? Oh yes, crazy!

@ oliverjames
You may have problems with the kernel, but your large problem is
fsck.ext3: Unable to resolve 'UUID=2e03d251-f899-413d-b2b8-894b5bdce67c'
fsck.ext3: Unable to resolve 'UUID=32ac3c0b-cb48-4b3f-9161-7f6b1bbfd843'
fsck died with exit status 8

This is not going to be fixed with a different kernel I'm afraid. It's the dreaded UUID syndrome :(
You must have changed your disks so they got a new UUID, or the new kernel gave them a new UUID.
Check in /boot/gub/menu.lst and /etc/fstab for these UUIDs
Change the lines where they are so that it is the /dev/sdx you see directly above them that is used. Begin with fstab as you won't see the /dev in menu.lst. Remember you must be root to change these files.
If you need more help don't hestitate to post back

Hi Husse,
I have the same exact problem; I tried 4 or 5 times to install Cassandra on the second hard disk of my PC, and every time it breaks down with the UUID error message, usually after a few days of use, with or without upgrading the kernel.
If I reformat the hard disk and recreate the partions, will I be able to solve the problem?
By the way, my main OS is Bianca on my first hard disk and it works flawlessly.

Strange. I don't have this problem.

Yes this is a known problem. One finds on the Web much of anybody complaining about that, each update of the kernel 2.6.20 changing the disk identification. :evil: See for example http://www.thejemreport.com/mambo/content/view/309/122/1/19/

As a matter of fact, I have experienced some moody behaviors with Ubuntu Feisty (Beta):

* kernel 2.6.20-12: IDE (PATA) /dev/hda goes /dev/sda
* kernel 2.6.20-13: IDE (PATA) is seen again as /dev/hda
* kernel 2.6.20-14: IDE (PATA) /dev/hda goes again /dev/sda


Stupid no? As the author says: "the Linux kernel shoud have had a new tagline: «How Do You Want Your Devices To Be Called Today?»" :roll:

Bad thing by the kernel team. :twisted:

wow... I don't have that problem either. :P

My devices have always been /dev/sdX in Gentoo, and Mint using the Intel ICH chipsets. Dunno why it keeps changing for you guys. Maybe I'm just lucky. :lol:

@ Kladiator
I have missed this thread lately - a reformat may or may not solve the problem - that is really ugly :(
As you see some have and some don't have this problem. I think it has to do with exactly what hard- and software you are using. All combinations don't use the same parts of the code (don't ask me to expand on this :) I know what I'm talking about, but to explain in simple terms....)

Hi Husse,
I can confirm that even a reformatting does not solve the problem but now I know the cause is a Fiesty-related bug, because on the same root and home partitions where Cassandra and Ubuntu 7.04 break down I installed the old Dapper and it works perfectly.
I guess I'll keep using Bianca until the next release of Linux Mint based on Gutsy Gibbon.

As I said in my last post I believe it's about the kernel 2.6.20-*

2.6.19 had already some problems:
Coming after a 2.6.19 kernel that was breaking all distros older than ten months
(http://www.thejemreport.com/mambo/content/view/309/122/1/19/)

For that see http://lwn.net/Articles/193603/

Wow. I'm surprised this is still happening. Only that first infamous kernel update caused problems for me. All later updates have been fine. Odd?

Have you edited your fstab file? There was a 2nd issue with the kernel updates switching the /dev/ ID back and forth between hd & sd, but this only affected people that had edited their fstab and removed UUID.
