Hi Dave, I've tested your patch and crash no longer segfaults. As for the various errors from "shifting sands"; I still see quite a few "free list: bad slab pointer:" and "partial list: bad slab pointer:" errors for my kmem_caches on both the live and vmcore crash sessions. Are you saying I shouldn't see many of these errors any more? Or are they still to be expected based on your experience when interacting with my vmcore?
