when I try to run Ubuntu on Hyper-V virtual machine, it gives me this error and doesn't let me continue:

piix4_smbus 0000:00:07.0: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr

what exactly do I have set up wrong? i'm giving it a 64gb hardrive with 1024 startup ram and 512mb - 4096 dynamic ram. If you need more information, please let me know how to find it as i'm just starting out using this.

I had the same error trying "Ubuntu 12.04 Desktop 64 bits" on Hyper-V 2008 R2 when chosen to just try Ubuntu.

  • First ensure your Hyper-V is up-to-date.
  • Then install Ubuntu basically in your VM but don't choose to run installation updates
  • Next time you will run its updates. SMbus bug will fixed. Worked for me.

Not sure why this happens, but I can confirm this worked for me using Ubuntu 12.04.2 on Hyper-V.

Basically, they are instructions on disabling the i2c_piix4 module.
