When all kernel debugging is enabled (lockdep, KSAN, etc), the function graph enabling and disabling can take several seconds to complete. The function_graph selftest enables and disables function graph tracing several times. With full debugging enabled, the soft lockup watchdog was triggering because the selftest was running without ever scheduling. Add cond_resched() throughout the test to make sure it does not trigger the soft lockup detector.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
