    Subject2.6.30rc7: ksoftirqd CPU saturation (x86-64 only, not x86-32) (e1000e-related?)
    From
    Date
    I've just compiled a 64-bit kernel for a couple of quad-core Nehalems
    (one L5520, one Core i7) for the first time. Both were using 32-bit
    kernels happily before, and one (the Core i7) is happy afterwards: but
    the other sees two ksoftirqd threads saturating the CPU (well, half of
    it, this being a 4-core box).

    Magic sysrq says:

    So, not particularly informative.

    CPUs 3 and 5 seem to be receiving the lion's share of the local timer
    interrupts and networking interrupts (this box has twin e1000es):

    I'd not expect that level of e1000e interrupt activity to flood the
    ksoftirqds like this, and in 32-bit mode it doesn't.

    So, anyone know what's going on, or how I could find out?


    The kernel is git head, 3218911f839b6c85acbf872ad264ea69aa4d89ad. Both
    the kernels that work and this one that doesn't were built by GCC
    4.4.1-prerelease, git head as of today. Modules loaded, only these,
    apparently pulled in by udev or something:
