48063 Rev. 3.18 October 2012 Revision Guide for AMD Family 15h Models 00h-0Fh Processors 673 Misaligned Page Crossing String Operations May Cause System Hang Description A misaligned Move String or Store String instruction with a REP prefix that crosses a page boundary may cause a system hang. This may occur when the TLB entry for the leading page is evicted while the string operation is executing, or the trailing page of the string operation crosses into a large page (1 GB or 2 MB) which requires an address translation due to a TLB miss. Potential Effect on System Unpredictable system behavior, likely leading to a system hang. Suggested Workaround Contact your AMD representative for information on a BIOS update.
