I looked at several of these. There are 2 major things going on:

- systemtap can't find module debuginfo
- systemtap can't seem to parse the output of `uname -i`

The bz6503 failure happened because systemtap couldn't find the module
debuginfo.

There is something odd going on with your kernel/system. 'uname -i'
isn't returning anything the testsuite recognizes, which leads to the
following:

Makefile:579: /lib/modules/3.10.1-trace+/build/arch/unknown/Makefile: No
such file or directory

The ipaddr.exp failure is also weird. The test script runs 'nc' to
generate some network traffic, but none is seen. Once again systemtap
complains that it can't find the "sunrpc" or "nfs" module debuginfo.

Does your kernel have those configured in?

The preprocessor.exp is a result of another failure to understand your
kernel architecture.

The fib.exp failure is probably PR15783.

The nfs errors are related to the fact that stap couldn't find NFS
either compiled into the kernel or as a module.

The scsi errors are related to the fact that stap couldn't find SCSI
either compiled into the kernel or as a module.
