BTW, I agree with this. It is better to have a quick way to grab the
ftrace buffers when a crash happens, as serial is excruciatingly slow.
Although, currently I still use kexec/kdump, but as Namhyung said, it
depends on crash being up to date. I tend to be sending in updates
every time I have to use it.
