FIX: After you install SQL Server 2008 SP1 for the IA-64 version of SQL Server 2008 with Event Tracing for Windows (ETW) installed, SQL Server hangs during startup and cannot be started

Microsoft distributes Microsoft SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.
SYMPTOMS
In the IA-64 version of Microsoft SQL Server 2008, you have SQL Server Event Tracing for Windows (ETW) enabled. However, after you install SQL Server 2008 Service Pack 1 (SP1) for IA-64, SQL Server may hang during startup and cannot be started.

Note This problem also occurs when you apply a SQL Server 2008 SP1-based cumulative update by using a slipstream installation.

This problem does not occur in the release version of SQL Server 2008.
CAUSE
This problem occurs because of a deadlock. One thread is grabbing the ETW provider registration lock, and because the ETW provider is enabled, the thread tries to load the DCOM in order to parse the XML configuration file. Meanwhile, another thread is supposed to initialize DCOM. On the other hand, this thread also loads the Shell32.dll file, which is waiting in its DLLMain function for the ETW Provider registration lock. This causes the deadlock.
RESOLUTION
The fix for this issue was first released in Cumulative Update 5 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:
975977 Cumulative update package 5 for SQL Server 2008 Service Pack 1
Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

Microsoft SQL Server 2008 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2008 Service Pack 1 hotfix to an installation of SQL Server 2008 Service Pack 1. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
