The test in src/testsuite/systemtap.samples/transport.exp for "transport fill staging buffer - relayfs" is consitently failing on ia64 and x86_64 machines. The previous test in the file does a systemtap script, but has no "-b". It passes. Looking at the relative sizes of the files: The probe2.out is from the "staging buffer" (-b) version and the probe.out is without that option. They generate a different amount of output: $ ls -l *.out -rw-r--r-- 1 root root 679758 May 23 15:57 probe2.out -rw-r--r-- 1 root root 678950 May 23 15:56 probe.out Martin says that the systemtap.samples/transport.exp is redundant. The systemtap.printf tests have finer grained testing. Probably should remove systemtap.samples/transport.exp.
This test has been removed and replaced by better tests.
