I don't think either of our recent commits caused that, neither I think that Pouria's recent changes to nd6_queue_timer() did. The easiest way to catch that would be to add assertion into softclock_call_cc() after the callout returned. Who runs the CI? What is the easiest way to reproduce this with the assertion without committing it to main? -- Gleb Smirnoff
