The Advanced Crash Dump Analysis and SPARC Architecture course provides students with essential skill to accomplish more detailed crash dump analysis than getting a stack trace and matching it to bugs. What re the common unique panic string panics, and what information needs to be looked at to determine the cause? What causes a bad trap to occur? Is there corrupt data or is there a hardware problem? This course alos presents information on analyzing user-forced crashes and live crash dumps. The latter part of the course includes information about the SPARC architecture and assembly language and explains how this information can be used to gather additional information from crash dumps.
