Would it crash your server once a day, every few days, or very seldom? By being clearly visible in the logs, did an oops appear in the logs each time you had to reboot your server? What happened when you installed the test kernel? Do you still see the oops for bug 1842037 appear in the logs? Or is it not present at all anymore, but you now suffer from bug 1828978 instead? If it was present before, but it is no longer present with the test kernel, it might mean the test kernel fixed bug 1842037. > NFS is still unstable but the problem seems to be in GSSD now plus in > Bug 1828978 . However, I can't tell you, if 1828978 happens in Xenial, only. I had a look at Bug 1829878, and I have started building a kernel which contains the commit you requested: commit 068feb42581a81de45ec49618c554243c07c800e Author: Trond Myklebust <trond.mykleb...@hammerspace.com> Date: Wed Jun 20 17:53:34 2018 -0400 Subject: NFSv4.1: Avoid false retries when RPC calls are interrupted The test kernel will be available from the same ppa as the initial test kernel, https://launchpad.net/~mruffell/+archive/ubuntu/sf241068-test in a few hours time, once it has compiled. The kernel which is currently building contains all three commits we were talking about. The two commits for Bug 1842037, and the above commit for Bug 1829878. Note, for 1829878, the 4.18 HWE kernel is no longer supported, so any fixes will be made available for the 5.0 HWE kernel. I will write to you tomorrow with instructions on how to install the test kernel, but if you are eager, they are the exact same as the previous test kernel, as the kernel version has not changed, as I just added the extra commit ontop of the last test kernel. Let me know if you have any questions, and let me know if you still see symptoms of bug 1842037 with the previous test kernel.
