Yup, I think that in this case modifying VTOP/PTOV should solve the problem. To solve this in generic way, is a bit harder. Maybe it is time to add some platform specific code to crash which can override these kinds of things? -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
