A reference for my future self for some interesting troubleshooting capability
When triggering the issue please issue as well a Alt+SysRq+t to dump a list of current tasks and their information to the log. (on systems where you do not have the SysRq key, it might be the PrintScreen one). You need to enable as well debugging dumps, so have to enable it:
echo 8 > /proc/sys/kernel/sysrq
then once you have triggered the crash issue a Alt+SysRq+t and provide the log got over the netconsole.
More information on SysRq key hacks: https://docs.kernel.org/admin-guide/sysrq.html
Lastly, since you have a efi system, we might take as well advantage of logging via pstore. It seems active on your system, so check on next crash please as well /var/lib/systemd/pstore directory for fresh crash logs.
For pstore: https://docs.kernel.org/admin-guide/pstore-blk.html and systemd-pstore.service(8).
