Hi Frank, I have tested the new test kernel and it boots successfully.
Please note this kernel is NOT SUPPORTED by Canonical, and is for TESTING PURPOSES ONLY. ONLY Install in a dedicated test environment. Instructions to install (on a bionic system): 1) sudo add-apt-repository ppa:mruffell/sf241068-test 2) sudo apt-get update 3) sudo apt install linux-image-unsigned-5.0.0-27-generic linux-headers-5.0.0-27-generic linux-headers-5.0.0-27 linux-modules-5.0.0-27-generic linux-modules-extra-5.0.0-27-generic 4) reboot 5) uname -rv 5.0.0-27-generic #28~18.04.1+hf241068v20191002b1-Ubuntu SMP Wed Oct 2 04:04:05 UTC If you get different output from uname -rv, you might be booted into the wrong kernel, and you will need to change your grub configuration. Let me know if you need help with this. Otherwise, this test kernel contains the requested patches for Bug 1842037 and Bug 1829878. Let me know how this test kernel goes, and if it fixes your NFS problems. If it doesn't, it would be good to upload some logs so we can have a better look.

This affects NFS-Shares that are protected by krb5* security. They become unusable until the system is re-booted. The problem is quite severe on terminal servers with multiple users - some of them not caring about refreshing their kerberos tickets.
