Your oopses seem to be the result of some kind of memory corruption. On the other oopses we could see the kernel oopsing on remove_page_from_hash_queue due to corrupted pointers (as Willy pointed out). Can you please try to crash your box again with CONFIG_DEBUG_SLAB=y Again, thanks a lot for your reports. - 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/
