Blue Screen on Windows 2008 R2 – “0x00000101 – CLOCK_WATCHDOG_TIMEOUT”

Symptom: A computer running Windows 2008 R2 with the Hyper-V role installed will randomly blue screen.  The blue screen error contains the message:

"0x00000101 - CLOCK_WATCHDOG_TIMEOUT"

The affected server is equipped with one or more Intel Xeon 55xx series processors or a Core ix desktop processor.

Problem: According to Microsoft, these Intel processors “generate incorrect interrupts” and cause the problem.

Solution: Make sure the server is up to date.  Microsoft has released a hotfix as well as an update distributed via Windows Update that fixes this problem.  The update is included in the update rollup package for Hyper-V on Windows 2008 R2 (KB2264080).

More information, including the hotfix request link and a workaround in lieue of the hotfix, can be found at:  http://support.microsoft.com/kb/975530
