[SOLVED] Boot Error from Kernel Module (i2c_piix4)

System Info:

Linux kk-archvm 4.2.5-1-ARCH #1 SMP PREEMPT Tue Oct 27 08:13:28 CET 2015 x86_64 GNU/Linux

This is running as a guest OS under VMWare Fusion 8.1.0, UEFI boot (rEFInd boot manager).

When booting, I see the following issue:

piix4_smbus 0000:00:07.3: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr

I've done a bit of searching, and for Virtualbox the fix seems to be blacklisting the kernel module and recreating the image. However, this does in fact seem to be a required kernel module:

00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 08)
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 08)

00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 08)
        Subsystem: VMware Virtual Machine Chipset
        Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
        Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
        Interrupt: pin ? routed to IRQ 9
        Kernel modules: i2c_piix4

Any ideas how I can fix this?

Thanks!

You don't need SMBus drivers if you don't know what SMBus is

Even if you know what it is you may still not care. But don't trust my word, read about SMBus on Wikipedia and see for yourself.

On many motherboards it's only used by BIOS to read identification data from RAM modules. On VMs it's perfectly useless.

I'll black list it. Thanks.
