Hi All

I am using openSuse 10.2.Recently, my computer started freezing regularly every evening at a certain time and the following messages started showing up during that time in var/log/messages:

I appreciate any help in elucidating what the problem is.

Your hard disk is failing, I would suggest backing up your data and replacing the disk.
