Can you verify this on your end?
Cannot reproduce either here, x86_64 host only. The report was from s390 host, though. I'm not familiar with the s390 patch, I wonder if any of you could use plain brain power to figure more things out. We could wait for 1-2 more days to see whether Thomas can figure it out, hopefully easily reproduceable on s390.. or we can also leave that for later. And if the current issue on such fix is s390-host-only, might be easier to be picked up by s390 tree, perhaps? In all cases, the regression is since 9.1, so maybe we don't need to rush anything in. -- Peter Xu
