Description of problem:
SELinux is preventing /usr/sbin/mcelog from read, write access on the chr_file msr.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that mcelog should be allowed read write access on the msr chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep mcelog /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
