Hi again, I still have problems after checking dmesg & syslog (which I had done before also). Apart from this problem I relly think lm_sensors would benefit from a 'make uninstall' target to clean up and uninstall. But thats a parenthesis... :) With your help #955 I successfully compiled p4b_smbus.o, but can't load it; panda:/usr/src/misc-drivers/lm_sensors-2.6.4/prog/hotplug# insmod p4b_smbus.o p4b_smbus.o: init_module: Operation not permitted Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters panda:/usr/src/misc-drivers/lm_sensors-2.6.4/prog/hotplug# and in syslog I get: Aug 15 11:54:07 panda kernel: i801smbus: SMBus already active BUT, a lspci does not show the SMBus controller (should have been at 00:1f.3 if I'm correct?) panda:~# lspci 00:00.0 Host bridge: Intel Corp. 82845 845 (Brookdale) Chipset Host Bridge (rev 04) 00:01.0 PCI bridge: Intel Corp. 82845 845 (Brookdale) Chipset AGP Bridge (rev 04) 00:1e.0 PCI bridge: Intel Corp. 82820 820 (Camino 2) Chipset PCI (rev 05) 00:1f.0 ISA bridge: Intel Corp. 82820 820 (Camino 2) Chipset ISA Bridge (ICH2) (rev 05) 00:1f.1 IDE interface: Intel Corp. 82820 820 (Camino 2) Chipset IDE U100 (rev 05) 00:1f.2 USB Controller: Intel Corp. 82820 820 (Camino 2) Chipset USB (Hub A) (rev 05) 00:1f.4 USB Controller: Intel Corp. 82820 820 (Camino 2) Chipset USB (Hub B) (rev 05) 00:1f.5 Multimedia audio controller: Intel Corp. 82820 820 (Camino 2) Chipset AC'97 Audio Controller (rev 05) 01:00.0 VGA compatible controller: Matrox Graphics, Inc.

ARGh... I guess I found something. I was about to describe what happened if loading modules i2c-core, proc and so on and referr to ticket #601. He was talking about 82820 815e, I have 82820 820... :( I checked your page of supported busses and it wasn't there... Is there any chance you will support this? Thanks for all your help so far!
