FreeBSD tells you about an issue with your hardware.
You get errors in L2 cache of your CPU; fortunately for you, they are correctable
and corrected.
What problem about FreeBSD do you experience?

Don't do this :)

P.S. Why did you file this bug under amd64 category?  Have you tested how i386
version of FreeBSD works on the same machine?

You are probably getting correctable memory errors.  You can get spurious 
single-bit errors in modern systems.  If you get any uncorrectable errors or a 
high rate (10's of thousands per hour) of correctable errors, then your RAM 
may be failing.

Mark as awaiting feedback. This looks like it may be a hardware issue

Likely a hardware issue.
