There were some changes to the coretemp driver in 2.6.32 and 2.6.33, but these shouldn't affect older CPU models and would also not change the readout by a few degrees. You can check if the high temperature limit is the same - then you can assume the driver changes did not affect your system. If you want to double-check, feel free to download the standalone version of the coretemp driver from: http://khali.linux-fr.org/devel/misc/coretemp/ You can use that driver with both kernels. If the temperature readings are still different, then this means that the coretemp driver is innocent. > I think that because that temp. change fan is working more often. > > I'm using Lenovo ThinkPad T61. This suggests that the temperature increase is real and this isn't just a reporting issue. I suggest that you check in /proc/acpi/processor/*/power, the amount of time spent in C2 and C3 states. Also install powertop and run it on both kernels, see if 2.6.33 has more frequent wake-ups than 2.6.31. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
