    SubjectSLUB BUG: check_slab called with interrupts enabled
    Hi Christoph,

    last night I got an interesting backtrace running 3.0-rc3
    (Fedora Rawhide kernel package). Unfortunately netconsole
    seems to be incompatible with KVM at the moment, so I had
    to capture the oops on my digital camera and will be
    transcribing just the backtrace.

    Essentially, kernel 3.0-rc3 hit this bug:

    static int check_slab(struct kmem_cache *s, struct page *page)
    {
    int maxobj;

    VM_BUG_ON(!irqs_disabled());

    The call trace:

    check_slab
    alloc_debug_processing
    __slab_alloc
    kmem_cache_alloc
    bvec_alloc_bs
    bio_alloc_bioset
    bio_alloc
    mpage_alloc
    do_mpage_readpage
    ... followed by ext4 and VFS code, obviously innocent


    Is this a known issue, Christoph?

    If not, anything I can do to help debug/fix this?
