JSI Tip 9926. When Windows Server 2003 resumes from a C1 idle state, you may receive a STOP 0x0000000A BSOD?

When a Windows Server 2003 resumes from the C1 idle state, it may BSOD:

*** STOP: 0x0000000A (0x0f6ff8c0, 0x000000ff, 0x00000000, 0x8074867e)

The System event log mayl contain an entry similar to:

Source: System 
ErrorTime: HH:MM:SS
Category: (102)
Type: Error 
Event ID: 1003
User: N/A
Computer: <ComputerName>
Description: Error code 0000000A, parameter1 0f6ff8c0, parameter2 000000ff, parameter3 00000000, parameter4 8074867e.
This behavior may occur because of bugs in some CPUs.

If your BSOD is the result of a processor bug, the workaround is to prevent the processor from entering the C1 idle state:

1. Open a CMD.EXE window.

2. Type the following commands, pressing Enter after each line:

REG ADD "HKEY_LOCAL_MACHINE\System\CurrentControlset\Control\Session Manager\Power" /V IdleFrom0Delay /T REG_DWORD /F /D 5
REG ADD "HKEY_LOCAL_MACHINE\System\CurrentControlset\Control\Session Manager\Power" /V IdleFrom0IdlePercent /T REG_DWORD /F /D 200

NOTE: This defines that the system must be 200 percent idle for 5 microseconds, which is impossible.

3. Shutdown and restart your server.
