No Execute bug plagues Service Pack 2

Microsoft has acknowledged a bug in Windows XP Service Pack 2 that can cause repeated restarts in systems with AMD Athlon 64 or Opteron processors. The issue only affects systems that are enforcing SP2's Data Execution Prevention (DEP), otherwise known as No Execute or NX. Sigma Designs' Hollywood Plus DVD decoder apparently triggers the bug, although other applications may exhibit the same behavior.

Users afflicted by the bug can configure DEP exceptions for any offending applications. Removing Service Pack 2 is also an option.
