Hier Auschnitte aus der Kerneldokumentation zum i2c-piix4:

Do 'lspci -v' and see whether it contains an entry like this:

0000:00:02.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)
             Flags: medium devsel, IRQ 9

Bus and device numbers may differ, but the function number must be
identical (like many PCI devices, the PIIX4 incorporates a number of
different 'functions', which can be considered as separate devices). If you
find such an entry, you have a PIIX4 SMBus controller.

[...]

If you own Force CPCI735 motherboard or other OSB4 based systems you may
need
to change the SMBus Interrupt Select register so the SMBus controller uses
the SMI mode.

1) Use lspci command and locate the PCI device with the SMBus controller:
   00:0f.0 ISA bridge: ServerWorks OSB4 South Bridge (rev 4f)
   The line may vary for different chipsets. Please consult the driver
source
   for all possible PCI ids (and lspci -n to match them). Lets assume the
   device is located at 00:0f.0.
2) Now you just need to change the value in 0xD2 register. Get it first with
   command: lspci -xxx -s 00:0f.0
   If the value is 0x3 then you need to change it to 0x1
   setpci  -s 00:0f.0 d2.b=1

Please note that you don't need to do that in all cases, just when the SMBus
is not working properly.
