Re: [Crash-utility] SLES 9 Dump

You have to pass System.map since this vmlinux is not debug enabled. I never used crash to analyze lkcd dumps, but as Dave said, it is possible. Otherwise why can't you use lcrash shipped in this distro since you are analyzing SLES9 dumps anyway.

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.
