Having read that RHEL/CentOS 6.4 came with new VMware drivers I checked
whether this problem might perchance be fixed. It isn't.

In the meantime I got a report that Windows 8 (64 bit) showed a similar

So, updated problem matrix (ESXi build omitted as it has no influence):

Processor                E5620    E3-1230  E3-1270V2

Windows XP/2003/2008       ok       ok       ok

Windows 8                   ?        ?      Panic

CentOS 5.8                 ok       ok       ok

CentOS 6.2                 ok       ok       ok(*)

CentOS 6.3                 ok       ok      Panic

CentOS 6.4                 ok       ok      Panic

(*) keyboard shows panic blink but system works fine otherwise

Reminder of the problem description: trying to boot a VM with
CentOS 6.3 or later on a VMware ESXi 4 host with a Xeon E3-1270V2
processor fails immediately after GRUB, with the VM locking up,
console message:

Sep 11 17:21:31.498: vmx| PANIC: early exception 0d rip
10:ffffffff81038879 error 0 cr2 0

and ESXi log messages:
