> 1. If the error has raised a MCE, then we will dump stack anyway.

I don't see stack dumps for machine check panics. I don't have any non-standard
settings (I think). Nor do I see them in the panic messages that other folks send
to me.

Are you settting some CONFIG or command line option to get a stack dump?
