X.86 rebooted without proper shutdown

I’ve serius problem. in the last mouth the backbone router was rebooted without proper shutdown more times during the day. Now the problem is increased, since i have installed 3.15 version the router rebooted without proper shutdown and also it doesn’t go back up…the console display “kernel panic not syncing fatal exception in interrupt”!!!
Now i’ve downgrade the router to the version 3.13, I have uninstalled all unused packages, but the problem persist.
It’s impossible work in this conditions, desperately waiting for a solution!!!

Router X.86 details:

Intel SR1530AHLX

Single Sata disk
Intel Gigabit Ethernet interfaces server Adapter:

  • Intel pro/1000 MT/PT Quad port Server Adapter
