I will not be able to test this with the upstream kernels because this bug occurs during an installation using an iso image. So the kernel will have to be in the iso image for me to to further test this.

Install utah: sudo apt-add-repository -y ppa:utah/stable sudo apt-get update sudo apt-get install utah 2. Make the iso readable by the user utah 3. Run "sudo -u utah -i run_utah_tests.py -i /path/to/the/vivid-desktop-amd64.iso -p lp:ubuntu-test-cases/desktop/preseeds/encrypted_home.cfg lp:ubuntu-test-cases/desktop/runlists/encrypted_home.run -f /var/log/installer -x /etc/utah/bridged-network-vm.xml" Now the trace above could be seen. The installation log containing the kernel log is attached. Note: This is reproducible with vm's provisioned with 512 MB memory, which is the default value in /etc/utah/bridged-network-vm.xml in the host machine. With 1G RAM this kernel trace is not reproducible.
