Revision Guide for AMD Family 15h Models 00h-0Fh Processors 48063 Rev. 3.18 October 2012 636 Instruction Addresses Near Canonical Address Limit May Cause #GP Exception Description The processor may incorrectly generate a #GP exception when an instruction executes within a small window of the linear-memory address at the limit of canonical address space (0000_7FFF_FFFF_FFFFh: 0000_7FFF_FFFF_FFF2h) and multiple branch mis-predicts occur to a linear-memory address at the limit of canonical address space. Potential Effect on System In the unlikely event that the conditions for this erratum occur, an unexpected #GP exception may result in a program or system crash. Suggested Workaround None required.
