Description of problem:
Summary
    SELinux is preventing /usr/sbin/irqbalance (irqbalance_t) "search" access to
    net (proc_net_t).

Detailed Description
    SELinux denied access requested by /usr/sbin/irqbalance. It is not expected
    that this access is required by /usr/sbin/irqbalance and this access may
    signal an intrusion attempt. It is also possible that the specific version
    or configuration of the application is causing it to require additional
    access. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for net, restorecon -v net. There is
    currently no automatic way to allow this access. Instead, you can generate a
    local policy module to allow this access - see http://fedora.redhat.com/docs
    /selinux-faq-fc5/#id2961385 - or you can disable SELinux protection entirely
    for the application. Disabling SELinux protection is not recommended. Please
    file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this
    package. Changing the "irqbalance_disable_trans" boolean to true will
    disable SELinux protection this application: "setsebool -P
    irqbalance_disable_trans=1."

    The following command will allow this access:
    setsebool -P irqbalance_disable_trans=1

I tried to disable as suggest in setroubleshoot browser but error remains.
Also I tried as FAQ procedure for create policy avcs but it's no working I
receive error:
