We had another similar bug with the ra flooding thing comcast was doing but I think this is different. an strace would be good to have. opkg update opkg install strace strace -p t`pidof odhcp6c` 2> /tmp/strace.log wait a bit, do a control-c, send the log. I realize this is a very severe bug, but at one level, I'm happy - we're making 52 days of uptime without a problem! Next stop, YEARS.
