    Subject[Bug 653] New: i386 NUMA does not work on non x440/Summit
    http://bugme.osdl.org/show_bug.cgi?id=653

    Summary: i386 NUMA does not work on non x440/Summit
    Kernel Version: 2.5.68
    Status: NEW
    Severity: normal
    Owner: mbligh@aracnet.com
    Submitter: ak@suse.de


    When a summit CONFIG_DISCONTIGMEM kernel is booted on a non summit/numa
    4cpu box it'll not boot, hanging before console init

    Enabling early printk shows that it gets to the numa memory init and then
    dies with an endless "unknown interrupt" loop.

    Looks like the srat discontigmem init fallback path does not work.

    This is also a problem with the dynamic subarchitecture path (only in -mm)
    when CONFIG_NUMA is enabled. It disallows to build a generic generic
    CONFIG_NUMA kernel.
