I started a git-bisect attempt, but there are several > unrelated problems, and I'm not sure this one is 100% reproduceable. It looks like it may be due to something pulled in with virtio updates. I've reproduced the problem on c8b0d7290657 "s390/virtio: change maintainership" but not on v4.11. Are there any known issues with those commits? I've just been doing this long-running bisect while working on other stuff. My reproducer (basically just running a bunch of NFS connectathon tests over a variety of protocol versions and security flavors) doesn't hit the bug reliably, and I've had to restart a couple times probably due to false negatives. But this looks pretty promising, and there's only 17 commits in that range, so I'll keep bisecting. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
