It could be possible that the sysctl entry you're trying to set isn't there at
the time sysctl runs. I'm guessing this is due to a module being loaded by
Try running 'sudo sysctl -P' yourself. If this works, then sysctl needs to be
invoked again at boot, probably after hotplug gets run. You could then create
a new script that contains 'sysctl -P', and make sure it's invoked after
hotplug in your startup scripts.
