Not running mrouted but also have such multicast related messages:

This kernel hanged two times (long time after these messages) so I returned to
rawhide's one. SysRq was working though so I can try to get some information
before it dies. Unfortunately both hangs happened in graphic mode so I wouldn't
see the register dump.
