So, let's see where systemtap looked for the kernel's debug file (which sho=
uld
be at /usr/lib/debug/lib/modules/`uname -r`/vmlinux on a RHEL-type system):

=3D=3D=3D=3D
grep ^open strace_err.txt  | fgrep ENOENT | fgrep
'"/usr/lib/debug/lib/modules/' | fgrep vmlinux
open("/usr/lib/debug/lib/modules/4.9.70-1.el7.centos.x86_64/vmlinux.debug",
O_RDONLY) =3D -1 ENOENT (No such file or directory)
open("/usr/lib/debug/lib/modules/4.9.70-1.el7.centos.x86_64/vmlinux", O_RDO=
NLY)
=3D -1 ENOENT (No such file or directory)
=3D=3D=3D=3D

So, where is the vmlinux file provided by your kernel-lt-debuginfo package?
