A few questions: 1) Just to check , you are emulating arm64 on amd64, correct? 2) Can you gather logs of the hung arm64 instances? Crashdump, tail -f /var/log/kern.log until it hangs, etc, etc 3) What kernel version are you running on the arm64 instances?

Many hang just running ntpdate right off the bat. William Grant had more direct tests he did, but upgrading from 3.13 to 3.19 didn't seem to fix things.
