---Problem Description---
In Ubuntu16.10 Call traces and unrecoverable exception occurs when Transactional memory tests are executed in 32TB system.
Steps to reproduce:
1- Download tm tests from the link - 'http://ozlabs.au.ibm.com/~mikey/tm-test-le.tar.gz'
2- untar tm-test-le.tar.gz; make clean; make; ./runtests.sh
The system gives below call traces and goes down. [Not able to do ssh
and the console gets hung]
