I also believe it's a HW issue. Could you stop your autobuilder, until
you figure out what's going on ?

Having bogus build results really isn't helpful, as it gives a lot of
noise to analyze and triage to find out what are the interesting things
to look at.

However, I very much welcome an installation like yours as part of the
autobuilders, because you found out a number of issues that we had
never found so far, and those are very useful to fix.

Would be good.
