The issue with ubuntu powerpc is, it stores stripped kernel image
as vmlinu*x* under /boot/; and stap fails to find debuginfo from this
file. Stap uses this files as main elf and tries to find debuginfo
file having ".debug" extension i.e. vmlinux-RELEASE.debug
debuginfo file on ubuntu is installed as vmlinux-RELEASE (without
.debug extension). So stap fails to find the file.

From link: RELEASE. "
"Fedora/RHEL kernel packaging on ppc does use a plain stripped vmlinux
file to boot from, but installs this as /boot/vmlinuz-
Renaming vmlinux to vmlinuz can solve the issue.
