Kdump is a long existing method for acquiring dump of crashed kernel, however very few literatures are available to understand it's usage and internals. We receive a lot of queries on kexec mailing list about different issues related to the kexec/kdump environment.
In this presentation, we talk about basics of kdump usage and some internals about kdump/kexec kernel implementation. It includes end to end flow from kdump kernel configuration to crash analysis.
