Right, as the message states, you're trying to analyze a 32-bit
x86 vmlinux/vmcore with the x86_64 version of the crash utility.
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
I missed the part below about the Kerntypes file, which would
also have to be added to the command line above. I forgot about
Suse's use of "Kerntype" files as an optional source of debuginfo
data.
And if the vmlinux-2.6.5-7.321-bigsmp file is not exactly the
kernel that crashed, then you can try adding the System.map file
onto the command line as well. Although I don't know if that's
possible with this Suse setup.
Surely somebody this mailing list can be of some help here?
Dave
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.
