    In that case, the lockup is most probably really the PCI bus locking up
    due to some device not answering. Not a whole lot of debugging help from
    the kernel on things like that - you won't be able to get any information
    out of the system without a hardware reset which also tends to clear all
    memory ;(

    Likely no. Not a lot to do but trying to figure out why the -mm tree works
    for you (if I recall correctly) by checking which patch breaks things..

    Yup, narrowing down where exactly things go south is the way to do it.
