Title:
ubuntu_32_on_64 test crash Trusty 3.13.0-140 amd64 system
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Trusty:
Fix Released
Bug description:
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
Output:
