    I haven't seen an alpha with more than 2G of ram that we booted on. Is
    it possible that isp has never been tested with >4G ram?

    Secondly.. what release is this on? I'm wondering if the horrific
    busdma bugs in 5.3-RELEASE might be a problem if the machine does have
    >4G ram.

    Third, is this a machine ram size problem or a disk volume size problem?
    The original post was about a 131G FC volume and calculating the wrong
    number of sectors and the wrong sector size...
