The dynamic debug output is still not present.
Please apply the attached patch (you may need to adjust it for 5.15 -
the idea is to comment out the execution of _ON and _OFF) and boot
with the dyndbg in power.c enabled.
It should not crash this time, so you should be able to collect full
dmesg and send it (as an attachment, please).
