My initial suggestion was to just fix up the boot time array.
I think that's actually wrong. Just print the raw data and analyze it in user space.
.. I still think it's not the optimal solution, but fixing up the event data from the previous boot (*before* printing it, and entirely independently of vsnprintf()) would at least avoid the whole "mess with vsnprintf and switch the format string around as you are trying to walk the va_list in sync".
And that code that does the va_list and vsnprintf() tricks is going to be removed as soon as that patch set finishes going through my full test suite, and you are OK with the solution.
Again, that patch set is here:
