    The warnings look like i386, exactly what hardware is this? Is your
    kernel compiled for SMP or UP?

    The warning you're getting is that clean_tree_block expects this block
    to be locked, and giving out a warning because it is showing up as
    unlocked.

    So, hopefully you're on a UP kernel and my test for a locked spinlock is
    broken in that config.
