fsck died with nexit status 8

[L.V.Gandhi <lvgandhi@gmail.com>]

I get the above message while booting and halts for maintenance. I
have winxp, kubuntu also in the same machine.  I give root password,
umount /dev/sda9 which is root and do e2fsck /dev/sda9. I get msg
"Superblock last mount time is in future. Fix(y)?. I do y.Then iot
says /dev/sda9 clean. But if I reboot immediately, then also the
machine gets halted with same message?
Any idea why this occurs?
What is the solution?
