crash not showing "exception RIP" data

This document (7010206) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 1

Situation

When analyzing a crash dump with crash, the tool for analyzing the core dump, the backtrace doesn't show the exception frame. For example:

crash> bt
PID: 5919   TASK: ffff8805ea7ea1c0  CPU: 3   COMMAND: "hald"
#0 [ffff8805e94b7b50] machine_kexec at ffffffff81020832
#1 [ffff8805e94b7ba0] crash_kexec at ffffffff810876c0
#2 [ffff8805e94b7c70] oops_end at ffffffff8139b2f0
#3 [ffff8805e94b7c90] __bad_area_nosemaphore at ffffffff8102ddc5
#4 [ffff8805e94b7cc0] dput at ffffffff8111076a
#5 [ffff8805e94b7ce0] path_to_nameidata at ffffffff81107c0d
#6 [ffff8805e94b7d00] string at ffffffff811e5c49
#7 [ffff8805e94b7d50] page_fault at ffffffff8139a56f
#8 [ffff8805e94b7dd8] seq_escape at ffffffff8111a358
[snip]
should look like:
crash> bt
PID: 5919   TASK: ffff8805ea7ea1c0  CPU: 3   COMMAND: "hald"
 #0 [ffff8805e94b7b50] machine_kexec at ffffffff81020832
 #1 [ffff8805e94b7ba0] crash_kexec at ffffffff810876c0
 #2 [ffff8805e94b7c70] oops_end at ffffffff8139b2f0
 #3 [ffff8805e94b7c90] __bad_area_nosemaphore at ffffffff8102ddc5
 #4 [ffff8805e94b7d50] page_fault at ffffffff8139a56f
    [exception RIP: seq_escape+24]
[snip]
