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?)

My current kernel is compiled without any i2c support and I soley intended to use modules for this.


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!

Pontus
