It does sort of look like an alignment issue (and the fact that LVM makes it work is very suggestive of this), but I agree that it's surprising that that would make it not work at all. I don't have a quick answer for you, but since this is important for performance on other SSDs anyway I hope that we can do something about it for 9.10.
