this is where serial logging (or netconsole/netlogging) may be useful.
do you have DEBUG_STACKOVERFLOW and latency tracing still enabled? The combination of those two options is pretty good at detecting stack overflows. Also, you might want to enable CONFIG_4KSTACKS, that too disturbs the stack layout enough so that the error message may make it to the console.
