If function_graph tracer is enabled during kexec, we see the below exception in the simulator: root@(none):/# kexec -e kvm: exiting hardware virtualization kexec_core: Starting new kernel [ 19.262020070,5] OPAL: Switch to big-endian OS kexec: Starting switchover sequence. Interrupt to 0xC000000000004380 from 0xC000000000004380 ** Execution stopped: Continuous Interrupt, Instruction caused exception, ** Now that we have a more effective way to completely disable ftrace on ppc64, let's also use that before switching to a new kernel during kexec.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
