I tried again using kerntypes and it failed with a different error. # /RedHat/crash-6.1.0-X86/crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504 Kerntypes-2.6.5-7.321-bigsmp ... crash: cannot resolve "_stext" Eugene -----Original Message----- From: Ku, Eugene Sent: Tuesday, March 05, 2013 6:04 PM To: Dave Anderson Cc: Ku, Eugene Subject: RE: SLES 9 Dump Dave, I rebuilt 6.1.0 crash as you had suggested. # file /RedHat/crash-6.1.0-X86/crash /RedHat/crash-6.1.0-X86/crash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped I then ran it against the dump.

So just get the 32-bit x86 crash utility. If you can't find one, then you can try building one on your x86_64 host: $ wget http://people.redhat.com/anderson/crash-6.1.4.tar.gz ... $ cd crash-6.1.4 $ make target=X86 ... $ ./crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504 If the build fails, you can wget the crash-6.1.4-0.src.rpm file from the same location, and the rpmbuild -ba will alert you to the additional packages you need.
