No... Please define "completely useless". Is there a ton of
network traffic? If so, please produce a bzip2 binary tethereal
trace of the traffic. If the cpu is pined or the system hangs please
produce a system trace (i.e. echo t > /proc/sysrq-trigger).
Also what is the exact kernel version (i.e. uname -r).
