One of the arguments seems is that kdump might not work 100% of the
time and saving kernel messages atleast gets some information out

I think being able to save dmesg to NVRAM, in general sounds good to
me (if done in a relatively clean manner). Especially if we can get
rid of code taking locks and code path executed after crash is not
tool long and relatively easy to audit.
