FTR, I'm also having problems with the wily arm64 kernel on multi-CPU
machines. I filed that as bug 1531768 as the logs here look rather

A few questions:
1) Just to check , you are emulating arm64 on amd64, correct?

/var/log/kern.log until it hangs, etc, etc
3) What kernel version are you running on the arm64 instances?
