For future reference, this bug has been reported in Ubuntu KVM hosts outside of the specific kdump test scenario (i.e. when running actual VMs in production-like setups). The "kdump with multiple CPUs" case was discovered as an alternative that hits the same MMU context bug, without needing complex hypervisor setups or fancy configuration.
