Description of problem:
SELinux is preventing /usr/lib64/xulrunner/plugin-container from 'getattr' accesses on the sock_file /run/atieventsd.socket.

*****  Plugin mozplugger (99.1 confidence) suggests  *************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests  ***************************

If you believe that plugin-container should be allowed getattr access on the atieventsd.socket sock_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 pool /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
