Subject: Re: [ftrace] kernel panics during my attempt to use ftrace

Hi Steven.

Thank you for your very very kind response.
I can build a stock kernel (I usually did for my real hw): and I don't see problems on this.
The problem is the bitness. My only KVM-enabled machine, as far as I can tell, has a 32-bit CPU.
So This would be a different problem.
I'll let you know when I can continue: right now I am a little bit in trouble with my exams: but I hope I will be able to eventually cme back and test.

Below my cpuinfo just for the record.
Thank you very much,
Enrico
