I believe that has been fixed in the upstream version of crash: http://people.redhat.com/anderson/crash.changelog.html#4_0_6_2 - Fix/workaround for the "search -k" command option on relocatable 2.6-era ia64 machines configured with CONFIG_SPARSEMEM. Without the patch, an immediate segmentation violation occurs. (anderson, yzgcsu.com) Please download and test the upstream version of crash (4.0-6.3) and build it like so: # tar xvzmf crash-4.0-6.3.tar.gz ... # cd crash-4.0-6.3 # make ... # ./crash <vmlinux> <vmcore> Confirmed the upstream version fixed the problem. Thanks! *** Bug 463726 has been marked as a duplicate of this bug. *** Although crash version 4.0-7.2.1 (and 4.0-7.2.2) fixes the SIGSEGV problem with the 2.6.18-92.el5 dumpfile attached to this bugzilla (as shown above in comment #6), Cai Quan has uncovered another bug with the same command when run on a 2.6.18-116.el5 kernel. So the fix is incomplete: This is from duplicate BZ #463726: # crash /usr/lib/debug/lib/modules/2.6.18-116.el5/vmlinux /var/crash/2008-09-24-04:41/vmcore crash 4.0-7.2.2 Copyright (C) 2002, 2003, 2004, 2005, 2006, 2007, 2008 Red Hat, Inc.
