As a Technical Support Engineer on the Kernel team, one of the top tools I need is kdump and crash, both used to determine the cause of a kernel crash. In this presentation, I want to give an introduction on how kdump works and how it generates vmcores and how people can use crash to debug vmcores generated by kernel crashes. I will demo some basic scenarios where kdump is useful and, if time permits, some more advanced debugging techniques.
