Your kernel had an Oops!

This is the result of bad hardware or a kernel bug.
Your system may continue to function as normal, however
there is a good chance bad things are happening right now.
        Bad things include: files disappearing, daemons crashing,
        complete server crashs, disk corruption and many others.

You might want to check your RAM with memtest86 as this is
usually the cause of the problem.
