FIX: Deadlocks occur when you execute a stored procedure to alter a temporary table if lock partitioning is enabled in SQL Server 2008 R2 or in SQL Server 2012

Microsoft distributes Microsoft SQL Server 2008 R2 Service Pack 2 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 R2 Service Pack 2 fix release.
Symptoms
Consider the following scenario:
  • You execute a stored procedure that contains an ALTER TABLE statement to alter a temporary table in Microsoft SQL Server 2008 R2 or in Microsoft SQL Server 2012.
  • When you try to execute the stored procedure, threads try to access the temporary table at the same time.
  • The computer that you use to execute the stored procedure has 16 or more CPUs.
    Note This means lock partitioning is enabled automatically.
In this scenario, deadlocks may occur on the temporary table.
Cause
This issue occurs because the two sessions that are used to execute the stored procedure try to obtain locks on the same temporary table object when lock partitioning is enabled.
