RELEASE=19.3
CODENAME=tricia
EDITION="Cinnamon"
DESCRIPTION="Linux Mint 19.3 Tricia"
DESKTOP=Gnome
TOOLKIT=GTK

GRUB_TITLE=Linux Mint 19.3 Cinnamon
My home dir is mounted through nfs on a local server via nfs4 and krb5i.
When stressing the mounted directory or its sub-directories (sometimes starting firefox, sometimes starting thunderbird, nearly guaranteed when compiling, sometimes the login itself), it will eventually lead to the following stack-trace. The corresponding process is then stuck and
accessing the mounted directory (like calling ls) easily yields further and similar stack trace and causing the process to also stuck.
Currently I am running an AMD 3950x on a ASUS Crosshair VII Hero Wifi (chipset x470).
I installed Ubuntu 20.04 LTS Desktop to check if the newer kernels (5.4 + 5.6) work without issues, but sadly, they **do not**.
With a little compile-stress-test, I have tested the following kernels which seem to run fine:
* 4.15.0-69
* 4.15.0-70
* 4.15.0-72
* 5.0.0-32
* 5.0.0-47 (current daily driver, runs without a hassle, max test length >7d - I am writing this bug report on it)
* 5.4.0-32-generic #36-Ubuntu from the proposal https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/19306320
* 5.6.0-1010-oem #10-Ubuntu SMP
* 5.7.0-050700rc6-generic #202005172030
But the following kernels do not run stable:
* 5.3.0-51 (Linux Mint 19.3 HWE)
* 5.4.0-28 (Ubuntu 20.04)
* 5.4.0-31-generic #35-Ubuntu
* 5.6.0-1008 (Ubuntu 20.04 OEM)
