ESXi 5.1 PSOD #pf exception 14 in world


   I am using HP BL460G7 and BL620cG7 hardware for ESXi 5.1 fresh installation. The OS has been installed successfully on all 6 hardware. 01 BL 620C G7 server is rebooting almost every day for a week and throwing PSOD as attached with the message #pf exception 14 in world.  The OA and Blades are running with latest firmwares.

VMware is aware of this issue.

To workaround this issue, reboot the host. Rebooting the host restarts the counter and eliminates the risk of any failure.
To avoid a reboot, you can check to determine if your system is at risk.
To determine if your system is at risk, run this script in the ESXi command line:

highWID=$(vsish -e ls world | sed 's!/$!!' | sort -n | tail -n 1)
let microFull=highWID/7400
echo ${microFull}
If this script returns a value close to 100,000, it is recommended to schedule a reboot.
I was able to keep my system active after disabling Hyper Threading and Turbo Boost technologies from BIOS I solution is still awaited..
