Some eagle-eyed MVPs reported that Microsoft has issued a rollup-update for Windows Server 2008 R2 Hyper-V.  Microsoft is recommending the installation of the rollup update to avoid the described issues.  You’ll not that the affect CPUs in issue 1 and 3 are Intel CPUs.  The update rolls up 3 updates into one installer:

Issue 1 – KB975530
When a computer has one or more Intel CPUs code-named Nehalem installed, you receive the following Stop error message:

0×00000101 ( parameter1 , 0000000000000000, parameter3 , 000000000000000c) CLOCK_WATCHDOG_TIMEOUT
Note The Nehalem CPU for a server is from the Intel Xeon processor 5500 series and for a client computer is from the Intel Core-i processor series.

Issue 2 – KB974909
Consider the following scenario:

• You run a virtual machine (VM) on the computer.
• You use a network adapter on the VM to access a network.
• You establish many concurrent network connections. Or, there is heavy outgoing network traffic.
• In this scenario, the network connection on the VM may be lost. Additionally, the network adapter is disabled.
• Note: You have to restart the VM to recover from this issue.

Issue 3 – KB981791
When a computer has an Intel Westmere processor, you receive an error message that resembles the following:

STOP: 0x0000001a ( Parameter1 , Parameter2 , Parameter3 , Parameter4 ) MEMORY_MANAGEMENT
