Hi Trond, Starting in next-20190222 I have observed a regression with NFS causing some of our boards to fail to boot. Bisect points to your commit ... commit 0ffe86f48026b7f34db22d1004bc9992f0db8b33 Author: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> Date: Wed Jan 30 14:51:26 2019 -0500 SUNRPC: Use poll() to fix up the socket requeue races After reverting this on top of -next I no longer see the problem. I have not had chance to look any closer, but wanted to see if you had any ideas what might be the problem. Cheers Jon
