- Increment nmi_seen on each WDT expiry NMI (only when watchdog is logically STARTed and extension state is valid).
- If nmi_seen < n: intermediate — bk_wdt_start(next_slice_ms), clear s_nmi_occur (or equivalent) so the “second NMI hard hang” does not trigger on legitimate chained expiries; if int_mode with a user handler, do not call the handler on intermediates; return.
- If nmi_seen == n``: final — **reset nmi_seen`, then existing reset / PANIC / int_mode handler path.
