Issue 376: Unsynchronized TSC for cpu

Reported by Jerome Howard, Jul 16, 2014

Im running the VoodooTSCSync.kext modded for the 6-core Intel i7 
processor.  I have a 3930k OC @ 4.2GHz on all 6 cores with Turbo and 
all speedstepping turned off.  Im using a Gigabyte MB, 
GA-x79s-UP5-wifi rev 1.0.  I have 32 GB of 2133 MHz ram @ 1866 MHZ.  
Im running 2 GTX 670 4gb cards as well as 2 27" Dell 2713HM 
monitors @ 2560x1440 each, not sure if that matters, dont see how, 
but figure I'd list it.  Im running Mac OSX 10.9.4, but this has 
happened on 10.9.0, 10.9.1, 10.9.2, 10.9.3 and 10.9.4.  I haven't 
run anything older with this hackintosh so I don't know about 10.8.x 
...  Currently Im running the newest version of FakeSMC, and Im 
using NullPowerManagement vs a patched AppleIntelPowerManagement 
kext.  I've used both and it still happens.  Im available if you 
need me to provide any type of assistance.  The Unsynchronized CPU's 
have ranged from 1 CPU up to about 5-6, its just completely random, 
but on this newest install, its usually only between 1 CPU and 3 
CPU's unsynced...  The weird part is, there is no system slow down 
that I can detech and benchmarks are relatively good.  I get about 
22k geekbench 3 64 bit score.  Let me know if Im off base or 
anything...  Here is the message I get...  And for all I know, this 
could be normal..

Unsynchronized  TSC for cpu 1: 0x00011baca966fcee, delta 
Unsynchronized  TSC for cpu 4: 0x00011bacaa24d08e, delta 
Current tsc from rdtsc64() is 311903434893552. Rendezvouing..

I will attach my kernel log and bsmesg log also...

Does Current tsc from rdtsc64() is 311903434893552. Rendezvouing.. 
mean that its syncing them up? or is this indeed an unsynchronized 
problem?  Thanks for the help.
