We're using Havana on RHEL 6.5 - 2.6.32-431.17.1.el6.x86_64 and OpenVswitch openvswitch-1.11.0_8ce28d-1.el6ost.x86_64

RedHat kernel is panicking on Openvswitch (OVS). accompanied by "QEMU SOFT-LOCKUP" warnings on console. Does anyone have any suggestion for resolving this?

We found pretty good stability since disabling "GRE tunneling" on OpenVswitch. We also tried enabling "tuned" and updating to latest RHEL6.5 kernel but mostly feel as though GRE tunneling was causing our problems.
