Could you try the attached patch? Ok. That is a part of the problem. The other issue that I saw while testing is that the new slab allocator fails on 64 bit non NUMA platforms because the bootstrap does not work right. The size of struct kmem_list3 may become > 64 bytes (with preempt etc on which increases the size of the spinlock_t) which requires an additional slab to be handled in a special way during bootstrap. I hope I will have an updated patch soon. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
