The subject line says what the problem is. The periodic file system check that linux runs every few boot ups is freezing the computer. Other than that my computer appears to be working fine. Anybody know what I should do?

Re: File system check freezes my computer on boot up
Boot into single user mode - assuming that you can. If you can't, boot from a LiveCD. We need to see your /etc/fstab file.

Re: File system check freezes my computer on boot up
The computer boots fine as long as the file system check doesn't run. If I let it run, the computer freezes. I can hit Esc before it freezes and it will boot normally. I just don't know why the file system check is causing the computer to freeze.

Again, we need to see (so please copy/paste it) your /etc/fstab file. Can't help you if you continue to just state "I just don't know why..."Windows no longer obstructs my view.

Re: File system check freezes my computer on boot up
Sorry, because you said something about a LiveCD I thought that you thought I couldn't boot the computer. I can boot if I Esc out of the file system check before it freezes. Here is my fstab.
# /etc/fstab: static file system information.

Re: File system check freezes my computer on boot up
Comment out the last entry in /etc/fstab - the one for your cdrom. It isn't required, and likely is why the long delay during boot - the system is 'waiting' for a non-existant cdrom disc.Windows no longer obstructs my view.

Re: File system check freezes my computer on boot up
I commented out that line but the computer still seems to freeze when the file system check runs. The progress bar below the word Kubuntu stops moving but the hard drives light is on, indicating some activity. I let it go for 45 minutes last night but it never got through the file system check.

Re: File system check freezes my computer on boot up
This begins to sound like a hardware problem. I had a computer behave this way, it was caused by a defective motherboard which locked the system up after getting hot.Originally posted by ejazzkattComment

Re: File system check freezes my computer on boot up
Try booting from a LiveCD then issue fsck on your hard drive and see if it still freezes or you see some errors.Originally posted by ejazzkattComment

Re: File system check freezes my computer on boot up
When you reboot, opt to edit the boot line and remove quiet from the boot kernel line. This will remove the Kubuntu 'bar' and let you see the boot messages. What will be pertinent is the last line that displays when the drive appears to 'lock' on you.Windows no longer obstructs my view.

Re: File system check freezes my computer on boot up
How long have you waited before pressing esc to abort the fsck? I've seen quite long mount times with reiserfs, specially after a power failure. My explanation was that the transaction log was being replayed each time the disk was mounted, and my fix was to boot into single user mode and running a sync command after a successful mount.
Your filesystem is not reiserfs, but the long fsck times may still apply, perhaps.Comment

Re: File system check freezes my computer on boot up
I ran fsck from Parted Magic on my disc. I got this message
The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext3 filesystem (and not swap or UFS or something else) then the superblock is corrupt and you might try running e3fsck with an alternate superblock: e2fsck -b 8193 <device>
I tried running the alternate command but it just returned me to the same screen.
I don't know what this means or what I should do now. Help please!
