In fact, related - on our systems attempt to start qemu-kvm VM under 
kernel-3.10.0-1160.80.1.el7.x86_64 freezes any of 5 workstations with  dual E5507 (all worked OK 
under kernel-3.10.0-1160.76.1.el7.x86_64 and any previous version). The workstations with E5-2609, 
E5-2650 or E5-2630 are not affected - all of them run qemu-kvm VM under 
kernel-3.10.0-1160.80.1.el7.x86_64 without problems.

Any ideas?
