That email client has been sacked.

Reports are pretty new & shiny yet so yes I’m over explaining the logic.
To me, showing your work applies to other places besides math.

Exactly and no surprise as number of those involved in all of this helped
get kernelci off the ground.

Our aim is to have quick summaries either appended with the gory
details or pointers to it for those that care.

For me the x86 and arm64 results are trustable. We’re working on
getting 4.14-rc runs clean and then we’ll get after the ‘known
errors with 4.4 and 4.9 as well.

32 bit arm results are a bit new/shiny yet. That’s where I’m most
skeptical when something pops up.

Hope the perspective helps.
