Hibernate and resume was working fine on my Ubuntu 12.04 using tuxonice with hibernate script.

But now it crashes after an unexpected system shutdown due to power loss.

Now I can hibernate but when I try to resume it gives me nothing and freezes until I press the power button to force shutdown the laptop and start it again.

I tried to re install tuxonice, hibernate script but in vain.
It is highly appreciated if anybody can help me fix this problem as soon as possible.
Thanks in advanced.
