    SubjectRe: The stability crisis
    I think the problem may have something to do with the size of the oops
    information and how much is left on the screen. I am doing Alpha
    development here, and virtually every oops I get a) double oopses and b)
    leaves no traces in dmesg or the log. In this situation, the first oops
    is long gone before I can even see it, and the second one is more than
    half gone by the time it's done, which means what I see on the screen is
    close to useless. At present this is not a sufficiently critical issue
    for us that we need to dive in and debug them, and when it becomes one I
    suspect we'll wire up the serial line for a more persistent tracking
    device (like a serial printer, a la Ingo's suggestion elsewhere on this

    Just my $.02, and only for a part of the issues Linus notes.
