Jeff Mahoney suggested the kernel-desktop-devel-debuginfo needs to be installed.
However, this does not help:

linux-hyic:/var/crash/2012-05-30-10:29 # crash vmcore vmlinux-3.4.0-2-desktop.gz
crash 6.0.6
[...]
crash: vmlinux-3.4.0-2-desktop.gz: original filename unknown
Use "-f vmlinux-3.4.0-2-desktop.gz" on command line to prevent this message.
crash: /var/tmp/vmlinux-3.4.0-2-desktop.gz_jAl38c: no debugging data available
crash: vmlinux-3.4.0-2-desktop.debug: debuginfo file not found
crash: either install the appropriate kernel debuginfo package, or
copy vmlinux-3.4.0-2-desktop.debug to this machine
in /usr/lib/debug, there is no file named vmli*
Additionally, if really more than just kernel-desktop-debuginfo is needed to be installed, it should require the other needed debuginfo packages.
I tried a local build (with "osc build"). At the moment when
> Wrote: /home/abuild/rpmbuild/RPMS/x86_64/kernel-desktop-devel-debuginfo-3.4.0-3.1.x86_64.rpm
was displayed, "rpm -qlp" showed that the RPM contained only the
vmlinux-*.debug file. However, in the end, the vmlinux-*.debug file was
missing and the contents was similar to the package of update repository.
After update to 3.4.2-1.1 (x86_64, desktop), the file /usr/lib/debug/boot/vmlinux-3.4.2-1-desktop.debug is present in kernel-desktop-devel-debuginfo package and it can be used with crash. I didn't check other architectures and flavors. If we cannot put that single file into kernel-desktop-debuginfo? IIUC one without the other is not really useful (kernel-desktop-debuginfo without kernel-desktop-devel-debuginfo), so it should be in one package. If that's not feasible, can we let kernel-desktop-debuginfo require kernel-desktop-devel-debuginfo, so that old documentation still applies? Or it is useful on its own? Then we need to update the documentation... this bug is still in 13.1 / current factory. Affecting, amongst others, users trying to user systemtap. Please review comment#4, which seems to be the simple fix for this problem. I'm teaching people in my kernel-debugging classes now that they need to watch out for SUSE crazy setup, but nobody can understand why this does not work automatically "out of the box" and I have a hard time explaining why :-) The real workload for support will surely come once SLES12 ships with this "feature". What is preventing the suggested solution from comment#4 to be implemented? This should be finally fixed in the current Factory kernel (and SLE12 as well). the vmlinux.*debug file is now part of kernel-$flavor-debuginfo |
