The actual values from the measurements in an appendix would be helpful. Including the boot time breakdown for the 8 way. On your chart, the time saved column is distracting to me as it is extra data. On the relative percentage column if it could be kexec/full boot that would make it so that I wouldn't have to go back to the text to understand the column. Also on the kernel boot time, I think that you are talking about the kernel init time. So why not call it that? On future and ongoing work. The crash dump seems to be orthogonal to fast booting. I would like to see future and ongoing work that applies to fast booting.
