I thought about that before, but did not go with any actual actions.
kexec test needs a system reboot, Kdump is even harder to test, that is
the reason I hesitated about.

But since the breakage happens here and there frequently, it is time to
try it.  I think I will play with it, but I might be slow because of
other things,  welcome to post patches if anyone is interested :)

Thanks
Dave
