Looks like data cache ECC errors, meaning the CPU 0 is faulty.
Eventually if it's not replaced there will likely be some uncorrectable
errors and the system will likely crash.

I am facing similar, but different errors.

[root@turyxsrv ~]# mcelog

Repeats whenever I do any kind of operations...
How severe is ChipKill errors? Should I consider throwing away CPU 1
and get another one.
