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?

Title:
  openstack instances on arm64 lock up on polling and other situations
  fairly repeatably

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  While working on deploying arm64 builders in openstack, we found that
  it was pretty easy to wedge them.  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.
