Here are the steps I used to reproduce:

#if using proposed pocket kernel
https://wiki.ubuntu.com/Testing/EnableProposed

#Need to enable deb-src for proposed/updates for this work
sudo apt update
$ sudo apt-get source linux

#After source is pulled, build and run ftrace selftests
$ sudo make -C linux-5.4.0/tools/testing/selftests TARGETS=ftrace run_tests

I also tested on Ubuntu-5.4.0-70.78 and saw similar behavior with soft lockups, but have yet to replicate the crash. Though I don't feel I have evidence to indicate this is a kernel regression.
