Description of problem: When performing a manual test run in the farm, the v7 profiler test terminates with a backtrace. Disabling the profiler test allows the v7 test run to complete. Version-Release number of selected component (if applicable): kernel-rt-3.0.4-rt14.27.el6rt.x86_64 v7 Version 1.4 Release 30 How reproducible: Always Steps to Reproduce: 1. v7 clean 2. v7 plan --server rhel6-1.farm.hsv.redhat.com 3. v7 certify --mode auto Actual results: : running profiler on installing test from /usr/share/v7/tests/profiler into /tmp/v7-profiler-WJZn5h mkdir -p /tmp/v7-profiler-WJZn5h cp -a runtest.sh profiler.py Makefile Makefile /tmp/v7-profiler-WJZn5h cp: warning: source file `Makefile' specified more than once make: `build' is up to date.

Additional info:
Created attachment 529389 [details] log from v7 test run on rhelrt-11 in the farm
Created attachment 531593 [details] profiler patch adding exception handler The traceback is when the test is attempting to reset oprofile. Errors there can be ignored - the patch just adds an exception handler with a "pass" in the except block.
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: In v7 1.3, failing to umount /dev/oprofile may cause traceback when running profiler test, this issue has been fixed in v7 1.4, now no more traceback be printed when fail to umount /dev/oprofile and this failure is ignored in profiler test.
