Errata
Workaround: None identified.
Status: No Fix
D60. Debug Status Register (DR6) Breakpoint Condition Detected Flags May be
Set Incorrectly
Problem: The Debug Status Register (DR6) may report detection of a spurious breakpoint condition under
certain boundary conditions when either:
• A "MOV SS" or "POP SS" instruction is immediately followed by a hardware debugger
breakpoint instruction, or
• Any debug register access ("MOV DRx, r32" or "MOV r32, DRx") results in a general-detect
exception condition.
Implication: Due to this erratum the breakpoint condition detected flags may be set incorrectly.
Workaround: None identified.
Status: No Fix.
