Yeah, I saw a pretty fair number of irreproducible issues that are
probably hardware flake-outs. Of course you can't tell which are those
and which are low-probability software bugs for many moons...
I believe that a large fraction of the buildfarm consists of
semi-retired equipment that is probably more prone to this sort of
problem than newer stuff would be. But that's the price we must pay
for building such a large test farm on a shoestring. What we need to do
to deal with it, I think, is institutionalize some kind of long-term
tracking so that we can tell the recurrent from the non-recurrent
issues. I don't quite know how to do that; what I did over this past
weekend was labor-intensive and not scalable.
SoC project perhaps?
