If you are facing issue Clock offset issue then there will be problem with your ntp is not in sync.
To resolve follow some commands
Check in which host it is giving problem go under that host through CLI and
1. systemctl status ntpd.service (For checking the status, if its not working the it showing Inactive message)
2. route -n copy the ntp server ip address (You will find under Destination column)
3. ntpdate <ntp server ip address>
4. systemctl start ntpd.service (for starting & syncing your host, after firing wait for sometime)
5. ntpstat (for checking whether it is synchronized or not it should be in synchronized)
after performing above steps your Clock offset issue will get resolved.

P.S. Don't forget to create or move your current .config from previous kernel or create new .config. # cd /usr/src/kernels/linux-3.18.8 # cp ../linux-old-kernel-version/.config . # make oldconfig -j32;make modules -j32;make modules_install -j32;make install # Answer all question using just the default. Just enter through the kernel questions.
