After some troubleshooting, we've found that issue is only hit with kernel 3.10.0-693.11.6.el7. With kernel-3.10.0-693.11.1 it works fine.
Also, the problematic kernel worked fine before 10-January when some patches including kernel and kvm were applied in RDO Cloud.
Other finding is that it seems that only happen in instances with cpu model reported as:
model name : Intel Core Processor (Skylake, IBRS)
