We've observed an unbalanced dst_release() on an input route in v6.6.y.
First noticed in 6.6.22. Or at least that is how far back our logs go.

We have just started looking into it and don't have much context yet,
except that:

1. the issue is architecture agnostic, seen both on x86_64 and arm64;
2. the backtrace, we realize, doesn't point to the source of problem,
   it's just where the ref count underflow manifests itself;
3. while have out-of-tree modules, they are for the crypto subsystem.

We will follow up as we collect more info on this, but we would
appreciate any hints or pointers to potential suspects, if anything
comes to mind.

Hi! Luck would have it the same crash landed on my desk.
Did you manage to narrow it down?

Nothing yet. Will keep you posted.
