SL60 booting error (not grub), SL60 stops at the end of loading

[fabien]

Hi every one,

I have SL6.0 installed on a Dell computer. 2 weeks ago, I spent some time installing a NFS server on it, as well as Matlab and other tools and every thing was working fine. I let the computer powered on during one week (every one was on holidays), when I came back, I restarted it. It booted correctly, I could choose my OS in the grub, SL6.0 began loading, and at the end (when the laoding bar was full), it stopped!

I tried to restart it several times, it was always the same problem, no error message, nothing! The only thing I can do Alt+F4 to open the terminal... But I don't know what to search or what to repair. I looked at the boot.log file, there is nothing (there is only some information about the last successful boot, but nothing about my problem).

Which is weird is that no one touched the computer during last week... So how did the problem appeared?

I made a filesystem image with Clonezilla 2 weeks ago. So, I restored it on the same computer (and on another different computer), and I thought it would solve the problem. No, the same problem appeared! Which is really weird, because after making this image, I have been using the computer successfuly for 1 week... So how can the problem appear with this image?

I really understand nothing!
Here are some information you can (maybe) need:
kernell: 2.6.32-220
computer: Dell Optiplex 755
Clonezilla version I used to backup: 1.2.11

If you need more information, please ask me.
I hope someone will be able to help me.

Try this: in the grub menu, highlight your OS and hit 'e'. This will let you edit the parameters, Highlight the kernel line, hit 'e' again to edit that line. Remove the rhgb and quiet options. Hit 'enter' to finish editing, and then 'b' to boot.

This will get you a lot more output on the console, and you should see how far the boot is getting and where it's getting hung up.

Hi,
after upgrade to the latest SL6 kernel, I had similar issue on my Dell workstation = loading bar full and it stopped there.

The quickest and simplest solution that worked for me was- I boot from the previous kernel (one that worked before the upgrade), then I edited the /boot/grub/grub.conf to boot the previous stanza as default.

good luck

Thank you every one for your answers! (and sorry for the delay)
In fact, a colleague had another desktop with every thing I needed already installed, so he gave it to me and it is working fine. But, I also checked what you told me.
Booting on the previous kernel changed nothing. (the problem didn't appear when I upgraded the kernel, but a long time after).
I removed the rhgb and quiet options at the boot. Then, I could see that the system was stopping just after:
readahead-collector: sorting
readahead-collector: finished

I also noticed the hard disk had some bad sectors. I am beginning to think that the OS may have been installed on some of these bad sectors, was unstable and crashed, one day.

Could it be that?

Hi fabien,
I know in your subject header, it states "not grub", but I give you this link anyway.

I've got the same problem on my Dell Precision m6500. Haven't had time to sort it yet....will post when I do...

PS: I'm thinking of a clean install anyway, but I'd better find this before I do.
