I have a Linux box that I upgraded from 7.2 to 8.0. For some reason and on occasion, when you open up an application, the system freezes up to
the point that you have to do a hard reboot. However, when you do the reboot, the OS wants you to do a FSCK on the system which is usually no
problem, but in this case, it usually takes over two hours or more to do the check! Should I try to reduce the check time and the amount of files
being checked, or should I just try and do a fresh install of this system? Its a specialty machine with unique software so I?m trying to resolve as much as I can before I have to consider the extremes. Originally the complete install was done when the upgrade option "didn't work", and all but two data drives wereconverted from 7.2 to 8.0; A home directory and another data drive. Afterwards, this is when I started having problems. Initially, when the system comes back up and request an fsck, it will start with the following messages:

"unattached inode ########, connect to /lost+found?, yes
"inode ###### ref count is 2, should be 1, Fix?, yes.

These unattached inode numbers (#######) can go from 1 to over 300000 before the
darn thing finally is finished! Is there any way around this before
I have to take the drastic measure of going to RH9?

-Also-

Is it possible to go back to an older version of linux, say from 8.0 back to 7.2?

PS,
the machine is a Dell Demision tower.

You can avoid hard reboot by login to other available terminal. press alt+ctrl and any function key F1 to F6 and see if any terminal is available to login. Login as root or any user, give reboot command and ignore any warning message. You will be able to safely reboot your machine.

As for go back to older version, it has not been considered in Linux, and hence the only way you can do is save your Data, settings etc. and reinstall the OS. however, you can boot in to your previous Kernel, if you have preserve it while upgrading from 7.2 to 8.
