Comment 0 for bug 1744199

THIS IS A POTENTIAL REGRESSION

Steps:
1. Deploy a Trusty amd64 node (node pepe in this case)
2. sudo apt-get install git python-minimal -y
3. git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests -b master-next
4. git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
5. rm -fr autotest/client/tests
6. ln -sf ~/autotest-client-tests autotest/client/tests
7. Monitor the syslog with tail -f /var/log/syslog
8. AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_32_on_64/control.ubuntu

Result:
* The system will hang without any output in syslog. I can't see any error message from ipmi output as well.

This test can pass with 3.13.0-139
