I read the boot log slightly differently - I'm assuming that the
boot log is from the kernel which _will_ be kexec'd from, so we
don't yet know whether the patches work or not.

I looked at the oops, and it's in tasklet_action, but for some
reason the unwinder is unable to unwind and provide a backtrace,
so it's not very debuggable.

However, this is a useful backtrace for me in a different way:
to provide to people who want to deprecate the frame-pointer
based backtracing to prove why the unwinder based solution still
isn't up to the job.
