... this step (the latter being a prereq to the former) has been
ongoing since the middle of March, on just this branch. The
primary suspect imo is a bad backport of the XSA-368 fix, as the
very first failure (flight 160128) was with just this and the
gcc11 build fix. As this continues to take up osstest resources,
could one of you look into this more closely? From my looking at
it I can't exclude this is merely bad luck (it might be the
previously observed "guest fails to signal readiness for
suspending"), but since prior pushes didn't get delayed for this
long I'm not sure at all.
