Dmitry,
The bisection is probably wrong. Above mentioned commit is specific to mlxsw which is not even present in the provided kernel config.
I see that this also appears in the web interface [1] which might be misleading to some people. Might be worthwhile to add a command for syzbot that tells it that bisection is wrong?
