I'm not 100% sure but I think the signal 11 problem is result from the CPU errata. There is the invlpg related errata and it has been fixed in stepping sB0 (cpuid = 0x619). I have both sA0 (cpuid = 0x617) and sB0 steppings and the signal 11 problem occurs only with the sA0 stepping. So, I think it is same as the 0xf00f hacking. -----------------------------------------------+--------------------------+ KATO Takenori | FreeBSD | Dept. Earth Planet.
