Only early revisions of the P54C (75-200MHz) Pentium processors are affected: steppings B1, B3, B5, C2 and cB1 (or 1, 2, 4, 5 and 11) as reported by cpuid). MMX Pentia and later chips are OK as well as any systems using external i82489DX APICs (so far i486, P5 (60/66MHz) Pentium and P54C Pentium systems with i82489DX APICs has been found, AFAIK). Once I proposed the option to be user-selectable as an advanced CPU option ( does appropriate validation), but the proposal was rejected as incomprehesible to an average user doing a kernel build. -- + Maciej W.
