[my two cents]

I do see similar kernel panic while running ftrace testing on today's
Linux next-20230906 tag. This crash is from qemu-arm64.

Here I am providing steps to reproduced link and scripts by using tuxrun tool.

Script details,
=============
# To install tuxrun to your home directory at ~/.local/bin:
# pip3 install -U --user tuxrun==0.49.0
#
# Or install a deb/rpm depending on the running distribution
# See https://tuxmake.org/install-deb/ or
# https://tuxmake.org/install-rpm/
#
# See https://tuxrun.org/ for complete documentation.

BTW, when you ran these, did you apply:
