Need assistance with enabling the SMBus on an Intel 855PM 82801DB

Hello,


Hmm I cant see subsystem ID in host bridge, please can you do
lspci -v -v -v

You might try to edit quirks.c

Find this in the file:

static void __init asus_hides_smbus_hostbridge(struct pci_dev *dev)
{
        if (unlikely(dev->subsystem_vendor == PCI_VENDOR_ID_ASUSTEK)) {
                if (dev->device == PCI_DEVICE_ID_INTEL_82845_HB)
                        switch(dev->subsystem_device) {

And add one line there like this:

static void __init asus_hides_smbus_hostbridge(struct pci_dev *dev)
{
asus_hides_smbus = 1;
        if (unlikely(dev->subsystem_vendor == PCI_VENDOR_ID_ASUSTEK)) {
                if (dev->device == PCI_DEVICE_ID_INTEL_82845_HB)
                        switch(dev->subsystem_device) {

Build kernel and reboot. You should now have the smbus enabled.
Run sensors-detect to see if there is something useful.

If so please tell us so, and we will fix the quirk. If there is nothing we are sorry.


Regards

Rudolf
