Description of problem: debuginfo file for /boot/vmlinux-2.4.22-20.1.2024.2.36.nptlsmp is not in the correct place. The .debug file should be in /usr/lib/debug/boot. It is placed in /usr/lib/debug/lib/modules/2.4.22-1.2075.nptlsmp/vmlinux.debug. The debuginfo file should have the same basename and end up as /usr/lib/debug/boot/vmlinux-2.4.22-20.1.2024.2.36.nptlsmp.debug. It looks like the debug information is being extracted before the vmlinux is placed in the correct place. OProfile needs the debuginfo to map kernel samples back to source code. Version-Release number of selected component (if applicable): kernel-2.4.22-1.2075.nptl kernel-debuginfo-2.4.22-1.2075.nptl
