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

Thank you guys very much for your kind answers.
I can not prove it actually: but I think it's right. It seems upgrading binutils could have solved the problem.
I am sorry for my impreciseness: but in the actual Ubuntu kernel version, 4.4.0-31** ?, the problem seems fixed.
I can enable kernel tracing without hitting a panic.
Thank you very much for your help and replies.
