SMBus base address uninitialized.

Post by jptech »

I get this warning message on boot with Ubuntu 9.04 Server. It happens with both 32bit and 64bit.

Code: Select all

piix4_smbus 0000:00:07.0: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr
I can barely find any other posts where people are having this issue, so I'm hoping someone will have an idea of what it's complaining about and can help me get rid of it. My host system is Windows 7 64bit. I'm using VirtualBox 3.04 and have installed the v3.04 of the guest additions. My Windows 7 install is brand new and v3.04 was the first VirtualBox install (no upgrades).

I get the same problem too. I would suggest adding "force_addr=0xaddr" to the kernel params in /boot/grub/menu.lst (for grub legacy) or in /boot/grub/grub.cfg (Grub2)

*Edit* kernel param didn't work.

Does the guest still work?
IMHO If so I would not worry about it. VBox does not emulate your system but uses special code to achieve these things and the guest OS can complain but it still works.
I see this in my 9.10, and 10.04 on but it still works just the same.

I would guess that you need to supply a hexadecimal number in place of "addr" after "0x" that is why the parameter failed.

It is a minor kernel notification and has no barring on the operation of the guest. No fix required.

Do you have any technical documents that can collaborate the claim that a fix is not required?

To management, The alert message at boot is the emotional equivalent to a big red blinking light in a missile silo were the on site techs only explanation is, "thats not important".

I found this and it worked perfectly to disable the alert:
