Use 'bt' to get a stack traceback for the task that paniced. Use 'rd' to obtain the registers at the time of the panic. Use 'id %rip' (or 'id %eip') to get the instruction which caused the panic. Use 'md' to examine memory as necessary. Use 'cpu 2' to switch the debugger context to cpu 2 (or whatever core you want to look at the state of). Read and understand the intel architecture documents volume 1 2 and 3. The help command is useful. There are man pages in the kdb patch for all the commands. Read and understand. scott _______________________________________________ kdb mailing list [email protected] http://oss.sgi.com/mailman/listinfo/kdb
