Collecting data for hung system problems

Edit online
If the system hangs, collect diagnostic data that you can use to diagnose and resolve the problem.

Procedure

To collect diagnostic data for hung system diagnostics:

  1. Create a kernel dump.

    For more information about dump tools, see Using the Dump Tools.

  2. Include the following files for SUSE Linux Enterprise Server:
    • system.map
    • kerntypes
    • vmlinux (text)
    • vmlinux (debug)
    Include vmlinux (full) for Red Hat Enterprise Linux and Ubuntu.

    Always include DBGINFO, see dbginfo.sh - Collect information for debugging.
