Re: Hardware monitoring on Asus A6JM laptop

Hi Firas,

So you have an ICH7 and the SMBus controller is clearly disabled. It's
supposed to be device 00.1f.3 but it doesn't show up under lspci.
You're only chance is to patch the kernel an recompile. Do you feel
lucky today? :-)

Try the attached patch, recompile the kernel, install it, reboot, run
lspci and check if you can see the SMBus controller. I believe dmesg
should spit out some messages if a pci quirk is applied during the
boot process.

Let us know how it goes.

Re: Hardware monitoring on Asus A6JM laptop

Hi Juerg,

It went flawlessly :) After I patched and recompiled the kernel and
rebooted, sensors-detect detected my SMBus just fine.

Thanks for the help !

Very good! Could you please send the lspci -nnvv and sensors output?
Now we just need to get the patch into mainline...

Re: Hardware monitoring on Asus A6JM laptop

Hi all,

I dont think it is a good idea to enable the SMbus when they disable it. It has
the the chip ADT7463 which servers as thermal control for whole notebook. The
chip is in automatic mode. Fan full at 90C. Fans stop at 55C.

Perhaps ACPI methods poke with that chip too. First it must be check if they do!
If so, the access must not be allowed!

Rudolf

Re: Hardware monitoring on Asus A6JM laptop

Please can you send a dsdt.bin

cat /proc/acpi/dsdt > /tmp/dsdt.bin

and also cat /proc/ioports
(when SMBus driver is loaded)

Thanks,

Rudolf
