    Subject2.5.25ide24 BUG() in page_alloc.c::prep_new_page()

    Just got the below oops while running 2.5.25ide24 (using ext3). The BUG()
    triggered is the BUG_ON(PageDirty(page)); in

    Seems like a dirty page was leaked somehow...

    Note this is a highmem machine (1GiB RAM) with smp and preempt enabled
    (but hardware uniprocessor, hence the kernel being tainted).

    kernel BUG at page_alloc.c:182!
