Summary: SELinux is preventing /usr/lib/chromium-browser/chromium-browser "read" access on cpuinfo_max_freq. Detailed Description: [chromium-browse has a permissive type (chrome_sandbox_t). This access was not denied.] SELinux denied access requested by chromium-browse. It is not expected that this access is required by chromium-browse 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. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.
