Yeah, other people may encounter a similar issue, I've created https://bugzilla.kernel.org/show_bug.cgi?id=214989 for reference including the patch from Stuart.

I am not sure what Bjorn would say here, however personally I say that it would be nice if you do open a bug there, if you have a minute, as it might help someone else who would stumble into this issue - a lot of people searches through Kernel's Bugzilla as part of their troubleshooting.

Also, as this is a hang in 5.4, and a lot of people uses this kernel, it might warrant a back-port to stable and long-term kernels.
