Kernel problems

Every so often KDE kicks me out and returns me to the login screen. This time I check var/log/messages and found this: May 18 19:34:10 linux kernel: Unable to handle kernel paging request at virtual address 00896714 Followed by a whole bunch of stuff that seems to be Kernel related. Is there something I can do to repair my Kernel ? (or upgrade it maybe ?) Thanks, Digsy Send instant messages to your online friends http://uk.messenger.yahoo.com
