panic when adding 224 multicast route in netstart with -current



Using -current as of this morning I made an i386 kernel with the following
config.. It dies with panic: trap right after adding the default route, I
assume as it is about to add the 224 multicast route.... Using an Apr 20th
2.3 snapshot GENERIC kernel, this does not happen... To make things a little
more strange, this kernel does not panic *sometimes* after I boot with a
generic kernel.  I can make a -g kernel and supply a trace if someone's
interested, dmesg follows--
