This is not a regression (never worked) and the system does not crash.
The trace is only observed on a specific platform and only with kexec
which I assume nobody is using but our team (for development purposes).

Therefore, I prefer to route it via net-next. If users complain
(unlikely), I will send backports to stable kernels.
