Title:
test_too_early_vsyscall from ubuntu_qrt_kernel_panic crashes Trusty
3.13.0-140 amd64 system
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is a potential regression.
The system will hang when running the test_too_early_vsyscall from
ubuntu_qrt_kernel_panic test suite with the proposed 3.13.0-140
kernel.
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_qrt_kernel_panic/control
Results:
* The system will hang, no output from syslog. This test can pass with
3.13.0-139
Output with 3.13.0-140
