    "Unrecoverable" can quite easily mean "something really bad has
    happened, corruption imminent". So maybe you would want BUG/BUG_ON to
    restart the box there, the restart-on-panic should help you there.

    You're mail is not making a case for defining BUG/BUG_ON to a nop, which
    is what the discussion is about.
