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.
