I cannot see that link. I am not sure what is going on. Does it say
what signal killed it?

Does it sit there for an hour and timeout? If so, then I  did see that
myself once recently, when the Kconfig needed stdin, but I could not
quitetie it down. I think buildman would provide it, but sometimes
not, apparently. So it can happen when there is an existing build
there and your new one which adds Kconfig options that don't have
defaults, or something like that?

If that is it, you can repeat it by clearing out your .bm-work
directory then building just that board for one commit, then the next
(with the Kconfig change).

Buildman is supposed to handle this, of course. I'm not sure what has changed.

Simon
