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.

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 (current daily driver, runs without a hassle, max test length 2d 4h
33m - I am writing this bug report on it)
But the following kernels do not run stable:
* 5.0.0-35
* 5.0.0-37 (stack-trace above, as you can see 49s after boot will already
throw the error)
* 5.3.0-24

seem to run fine:

* 4.15.0-70
* 4.15.0-72
* 5.0.0-32 (current daily driver, runs without a hassle, max test length 2d

* 5.0.0-35
* 5.0.0-37 (stack-trace above, as you can see 49s after boot will already
throw the error)

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 (current daily driver, runs without a hassle, max test length 2d
4h 33m - I am writing this bug report on it)
But the following kernels do not run stable:
* 5.0.0-35
* 5.0.0-37 (stack-trace above, as you can see 49s after boot will already
throw the error)
* 5.3.0-24
