    After much testing, which is still in progress it would seem that
    *maybe* mjb4 does have the problem too, although it's much harder to
    hit. Please note that this is a single data point where for other
    kernels I have two or more occurrences of spontaneous reboots.

    I've been checking older kernels... it would seem the problem first
    occurs in 2.5.53 (that is 2.5.53 through 2.5.62-bk all reboot for me).
    2.5.51 doesn't appear to and thus far neither does 2.5.52.

    I say thus far, because the problem usually appears after about 15
    minutes of compiling, but it sometimes takes a little longer. I'm
    running 2.5.52 now and after 45 minutes it's still going.


    As to what difference it might be between '52 and '53 I have no idea.
    I had a quick look and the changes there are considerable.

    I've tried different compiles, with and without preempt, and and
    without IO-APIC and trimming down the kernel...
