Oh you do, OK good, it would be nice if I were able to reproduce it here.

Any particular thing that triggers it? Preferably without running X or
any proprietary software (eg. if you run a make -j128 kernel compile or
something that forces a lot of swapping, does that lock up?).

What filesystem? Can you also attach your .config

No luck getting a backtrace out of the NMI watchdog?

Thanks,
