As I have a couple systems that may/may not be affected, I'm seeking some clarification. Is this an effect of the errata published by AMD in the Athlon models 4 & 6 revision guides as "INVLPG Instruction Does Not Flush Entire Four-Megabyte Page Properly with Certain Linear Addresses"? That errata lists all Athlon Thunderbirds as affected and all Athlon Palominos except for stepping A5. Regardless of specific errata listings, will future workarounds be enabled based on cpuid or via a test for the bug itself?
