    Back to not booting with tiger_defconfig on Intel Tiger box :-(

    There are no lines like:

    On node 0 totalpages: 260725
    DMA zone: 129700 pages, LIFO batch:7
    Normal zone: 131025 pages, LIFO batch:7

    in the log ... which might explain the OOM later.

    Whole console log appended (The "Kill process 2" messages repeat
    forever).
