:SELinux is preventing /usr/sbin/sysctl from 'open' accesses on the file nmi_watchdog.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that sysctl should be allowed open access on the nmi_watchdog file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep sysctl /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Michal Ambroz 2012-04-04 23:43:58 UTC
Should be probably solved together with other events triggered by 
"tuned-adm profile something".

Marking as duplicate of 809832.
