    hm. Your crashes do seem to span multiple subsystems, but it always 
    seems to be around the SLUB code. Could you try the patch below? The 
    SLUB code has a new optimization and i'm not 100% sure about it. [the 
    hack below switches the SLUB optimization off by disabling the CPU 
    feature it relies on.]
