[CentOS] ESXi, CentOS 7 guest, CPU disabled

Hello,

Over the last several weeks I've had a couple of CentOS 7 guests running 
in ESXi freeze because the CentOS halted the CPU.  The problem is 
described here:

My CentOS 6 VMs are not misbehaving at all, nor are the Ubuntu VMs. 
Anyone else seeing this bug or know what to do about it?

Thanks,
Jack
