My theory is that it's a race and that it's thus timing dependent. TTY SMP details get stressed most during a particular point during bootup, when all the mingetty's are starting up all at once and race with each other. If you are lucky to not hit the bug then, then the likelyhood is much lower later on. It would be nice if Alan posted his TTY stress-testing code. It could potentially make this bug bisectable.
