Contains something awfully similar seeming to the sshd restart thing which
was just fixed on Debian:

However
http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-qemut-rhel6hvm-amd/ALL.html
suggests it is very rare though, much more so than the sshd issue.

I think it is specific to merlot and will work itself out next time. From
http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-qemut-rhel6hvm-amd/linux-3.18.html
there was one similar failure months ago which succeeded on a second attempt.
