Indeed i only get this the second time.

The first time i get

hartko@vwagwolkf320:~/dropwatch/src$ ./dropwatch
Initalizing kallsyms db
dropwatch> start
Enabling monitoring...
Kernel monitoring activated.
Issue Ctrl-C to stop monitoring

But Ctrl-C does not work. I only get 100% CPU load on the CPU executing dropwatch.

After killing the process, i get the above originally described behaviour.

And this comes every time, i invoke dropwatch.

I'm running a debian system here on a Dell 830 Laptop with Core2Duo and the
latest linux-2.6 git

Oliver

ps. Do i need to be root to run dropwatch?
