High CPU usage on 5.6.5

Hi.

I have a fortigate 90D that I have upgraded from 5.6.3 to 5.6.5. Before the upgrade I didn't have any high cpu usage problem. This is the output from diag sys top:

This issue was resolved updating the firmware to 6.0.2.  Now I have another issue.  At login, I'm getting the message 

File System Check Recommended.  Clicking on "Reboot and scan disk now",  reboot the fortigate but it never finish the reboot completely. It froze with the power led light only on and stay there. The only way to complete the reboot is to disconnect the power.  After that the unit boots again but gave me the same message again "File System Check Recommended".  What can I do?
