Steps to reproduce the problem:
1. ASRockZ68E7G3, i7-2600K, OS X Lion 10.7.2
2. Sleep. Wait. Wake.
3. Use OS X (if it didn't hang yet).
4. Goto "Step 2" above.
Expected result:
Working/responsible system after wake.
Actual result:
Not always working/responsible system after wake.
Reason:
Probably VoodooTSCSync use non-zero (non-master) core of i7-2600K
which leads to not sync other core's TSCs.
P.S. I have
<key>IOCPUNumber</key><integer>7</integer>
set in info.plist
