Hi Subrata/Cai, That's a very good idea.

Making sure all the kdump config options are working as stated. This is the interface a kdump user first sees and if it does not work, then it leaves a very bad impression. > == increase coverages for new kexec/kdump development efforts == > - new reserved region syntax in Kernel. Another important thing we need to focus on is driver testing. Drivers can fail to initialize in second kernel and kdump will fail. Can we do something so that we can do following. - Collect the machine statistics on which kdump was tested and send the reports to a common place. Especially capture the storage/network driver data which can be probably be available through LTP site. - Also capture how much memory was reserved on what architecture and whether it worked or not. This will help us verify for sure that how much memory to reserve for second kernel on various architectures.
