The crash is extremely easy to reproduce.

I've not observed any missed events on a kprobe on an arm64 system

My (limited!) understanding is that this suggests there could be a
problem with how missed events from a recursive call to memcpy are
being handled.

I think so too. BTW, could you bisect that? :)

Thank you,
