It is. We keep a close eye on it; it usually bootstraps (for at least the configs we test) all the time. Especially during stage 1 things do break from time to time, but that isn't unique to Power ;-) There isn't a rule that we can just revert any patches that break bootstrap on primary targets (and I am not suggesting there should be), so breakage now and then is unavoidable. Maybe some CI thing can help make stage 1 a less bumpy road. Segher
