A technique for creating memory page classification that improves memory dumping efficiency. In one example embodiment, this is accomplished by creating DPCs that substantially maps to operational hierarchy of kernel that includes modules/sub-systems that can allocate and manage the kernel. One or more DPCs associated with the kernel's modules/sub-systems that needs to dumped is then determined upon receiving a computer system panic condition. The memory pages associated with the one or more DPCs are then dumped to an external memory based on the determination.
