That might be the reason, but I was guessing No, i8kutils contains a user-space helper for the i8k module, and that's all. My changes to the i8k make it partly useless (on purpose). > the i8k modules dependencies were the came as emc6w201's. > There was nothing in the logs about any of this and no core file > for whatever is segfaulting.

But it could be that no core is written because the problem is in i8k itself and not in the user-space application. Unfortunately I have no idea how to investigate this further. This makes me feel sad because Luca's findings were very promising :( -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
