Subject: igmp broadcast storm Red Hat EL7 3.1 Kernel

When installing Centos 7 running kernel 3.1 (Centos 7 distro) the
system generates an igmp broadcast storm which locks up and knocks
down a Century Link DSL router.  Powering the router off clears the
broadcast storm.

The bug is kernel related and resembles very closely another bug seen
about 10 years ago with Caldera's distro's on 2.4.  The bug occurs on
the ia32 beta build.  The bug DOES NOT exist in the 64 bit x86_64
versions.    I will attempt to debug it further since I have my own
debugger and try to run it down and provide more info.
