Re: longrun utility error

Are they static or modules? If a module is not loaded
then you can get similar device errors. For example
if ALSA modules are not loaded the associated device
files aren't accessible. The /dev/cpu is kind of like
/proc in that its not a real device or filesystem.
Its a kernel thing. If you build those features
(CPUID and MSR) as statically included in the kernel
then I have no idea what is wrong. If you built them
as modules <M> instead of <*> then they need to be
loaded. Are they loaded? Do a lsmod. If not try
modprobing them, and add that to your init scripts.
The only other thing I can think of is if you are
using the /dev filesystem. That uses a daemon to
manages the /dev directory and sometimes you need
to configure that. Beyond that I have no idea, it
appears to look like an invalid parameter because
it says "invalid argument" but those kinds of
message are often misleading. Can you see the
device /dev/cpu and is stuff in there? If you
can't see it then its not a problem with the
longrun program, its still a problem with the
kernel devices (CPUID and MSR) or perhaps the
/dev filesystem (are you using devfs?).
